How to Use a Tenda Router as a WiFi Extender Using LAN Cable – Tenda 4G03 Pro Example

If you have an old or additional Tenda router and want to use it to extend your WiFi coverage, you may be able to connect it to your main router using an Ethernet or LAN cable. This can be a useful way to provide WiFi in another room, office, floor or area of your home.

In this guide, we will explain how to connect a Tenda router to another router using a LAN cable, how to configure the WAN/LAN connection, when to use Dynamic IP, what VLAN ID means, and how to configure the router as an Access Point when supported.

Example used in this guide: Tenda 4G03 Pro.

The exact menu names and available features can be different depending on the Tenda router model and firmware version.

Can a Tenda Router Be Used as a WiFi Extender?

Yes, many Tenda routers can be used to provide additional WiFi coverage through an Ethernet cable. However, the exact method depends on the model and firmware.

There are two common ways to connect a second Tenda router to your existing network:

• Access Point mode – the Tenda works mainly as a WiFi access point.
• WAN/Router mode – the Tenda works as a second router and creates its own network.

If your main goal is simply to extend WiFi coverage using a LAN cable, Access Point mode is usually the preferred setup when your Tenda router supports it.

What You Need

• A main router with a working Internet connection
• A Tenda router
• An Ethernet/LAN cable
• Access to the Tenda router's administration page

For this example, we are using the Tenda 4G03 Pro.

Basic Network Setup

The general network connection looks like this:

                    Internet
                       |
                       v
                +--------------+
                | Main Router  |
                +------+-------+
                       |
                       | LAN Cable
                       |
                       v
                +--------------+
                | Tenda Router |
                +------+-------+
                       |
                  WiFi Network

The Ethernet cable carries the Internet/network connection from the main router to the second Tenda router. The Tenda can then provide WiFi to devices in the nearby area.

Option 1: Use the Tenda as an Access Point

An Access Point setup allows the Tenda router to provide WiFi while the main router continues to manage the network, DHCP and Internet connection.

A typical Access Point setup looks like this:

Main Router
192.168.1.1
      |
      | LAN Cable
      |
      v
Tenda Router
192.168.1.x
      |
      +---- WiFi
      |
      +---- LAN Devices

In this configuration, devices connected to the main router and devices connected to the Tenda can remain on the same local network.

Access Point Configuration

If your Tenda router has an option called AP Mode, Access Point Mode or something similar, select that option.

The router may automatically configure the necessary settings.

If your model does not provide an automatic AP mode, you may need to manually:

1. Give the Tenda a suitable IP address in the main router's network.
2. Disable the Tenda's DHCP server.
3. Connect the main router LAN port to the appropriate Tenda LAN port.
4. Configure the Tenda WiFi name and password.

The exact procedure varies by Tenda model and firmware.

Option 2: Use the Tenda as a Second Router

Another option is to connect the main router to the Tenda's WAN port. In this configuration, the Tenda acts as a separate router.

Main Router
192.168.1.1
      |
      | LAN Cable
      v
Tenda WAN
192.168.2.1
      |
      v
    WiFi

The Tenda receives an IP address from the main router and creates its own local network.

This method is useful when you want the second router to manage its own network. However, it is different from using the Tenda purely as an Access Point.

Which Tenda Port Should You Use?

The correct port depends on the Tenda model and the configuration you are using. Some Tenda routers have separate LAN and WAN ports, while other models have a combined WAN/LAN port.

For example, on the Tenda 4G03 Pro, the WAN/LAN port can be used for the Ethernet WAN connection when the appropriate WAN/Failover configuration is enabled.

For a WAN connection, the typical arrangement is:

Main Router LAN
      |
      | Ethernet Cable
      |
      v
Tenda WAN/LAN

Always check your particular Tenda model's documentation because the port functionality can vary between models.

Example: Tenda 4G03 Pro WAN Configuration

On the Tenda 4G03 Pro, the Ethernet connection can be configured through the router's Internet/network settings. One of the available settings is Failover.

When using the Ethernet connection as the WAN source, enable the appropriate WAN/Failover function if required by your firmware.

You may then see connection types such as:

• PPPoE
• Dynamic IP Address
• Static IP Address

What Connection Type Should You Select?

Dynamic IP Address

For most normal connections from an existing router, select Dynamic IP Address.

Dynamic IP means that the Tenda automatically receives its network information from the main router using DHCP.

For example:

IP Address: 192.168.1.20
Gateway:    192.168.1.1
DNS:        Automatic

The actual IP address will depend on the network configured by your main router.

PPPoE

Choose PPPoE only when the upstream Internet connection specifically requires a PPPoE username and password.

For a normal LAN connection from an existing router, PPPoE is generally not required.

Static IP Address

Choose Static IP Address when the network administrator or Internet provider has given you a specific IP address, subnet mask, gateway and DNS information.

Do not use a random static IP address because incorrect network settings can prevent the connection from working.

What Is VLAN ID?

Some Tenda routers may display a VLAN ID option during WAN configuration.

A VLAN ID identifies a specific Virtual LAN on a network. VLAN tagging is commonly used by some Internet providers and managed networks.

If your main router provides a normal Ethernet connection and your network does not require VLAN tagging, you should normally:

• Leave VLAN ID disabled or blank.
• Do not enter a random VLAN number.
• Use the VLAN ID provided by your ISP or network administrator if VLAN tagging is required.

Recommended Settings for a Normal Ethernet Connection

Setting	Recommended Configuration
Connection Type	Dynamic IP Address
VLAN ID	Disabled / Blank unless required
DNS	Automatic
Ethernet Source	Main Router LAN Port
Tenda WAN Connection	WAN/LAN port when configured as WAN

How to Configure the Tenda WiFi

After establishing the wired connection, open the Tenda WiFi settings.

You can configure:

• WiFi network name (SSID)
• WiFi password
• Wireless security
• 2.4 GHz settings
• Other wireless options supported by your model

For example:

WiFi Name: Office-WiFi
Password:  YourStrongPassword

You can use the same WiFi name and password as your main router in some Access Point configurations. Alternatively, you can use a different name to easily identify the Tenda WiFi network.

How to Check If the Tenda Has Internet

After connecting the Ethernet cable and saving the settings, open the Tenda Internet or WAN status page.

If the connection is working, the Tenda should receive network information from the main router.

For example:

WAN IP: 192.168.1.20
Gateway: 192.168.1.1
DNS: Automatic

If the Tenda receives a valid IP address and gateway but WiFi devices still cannot access the Internet, check the Tenda's LAN and DHCP configuration.

What If the Tenda WiFi Works but Internet Does Not?

If your phone or laptop can connect to the Tenda WiFi but there is no Internet, try the following troubleshooting steps:

1. Confirm that the main router has working Internet.
2. Test the Ethernet cable with another device.
3. Make sure the Ethernet cable is connected to a LAN port on the main router.
4. Check that the correct Tenda Ethernet port is being used.
5. Check the Tenda WAN/Internet status.
6. Use Dynamic IP if the main router provides DHCP.
7. Leave VLAN ID disabled unless your network requires VLAN tagging.
8. Restart both routers if necessary.
9. Check that the Tenda has received an IP address and gateway.

Should I Use the Same WiFi Name?

You can configure the Tenda with the same SSID and password as the main router in some network setups. This can make it easier for devices to connect to the available WiFi network.

However, using the same WiFi name does not automatically create a true mesh network. The roaming behavior depends on the routers, WiFi standards and configuration.

If you want to easily identify the second router, use a different WiFi name such as:

Main WiFi:  Home-WiFi
Tenda WiFi: Home-WiFi-2

Can I Use a Tenda 4G LTE Router Without a SIM Card?

Some Tenda 4G LTE routers can also use an Ethernet connection depending on the model and configuration. The exact functionality depends on the router's firmware and supported operating modes.

For the Tenda 4G03 Pro example used in this guide, the Ethernet WAN functionality can be configured through the appropriate network settings.

Access Point vs Second Router

Feature	Access Point	Second Router
Same local network	Usually yes	Usually no
Main router handles DHCP	Yes	No, Tenda normally handles its own LAN DHCP
Uses Ethernet cable	Yes	Yes
Useful for extending WiFi	Yes	Yes
Separate network	No	Yes

Frequently Asked Questions

Can I use any Tenda router as a WiFi extender?

Not every Tenda router has exactly the same features. Check whether your specific model supports Access Point, Repeater, WISP, WAN or other relevant operating modes.

Can I connect two Tenda routers using a LAN cable?

Yes, provided the routers have compatible Ethernet functionality. The second router can potentially be configured as an Access Point or as a separate router depending on the model.

Which port should I use on my Tenda router?

This depends on the model. If the router has a dedicated WAN port, use it for a WAN connection. If it has a combined WAN/LAN port, check the router's configuration to determine when that port operates as WAN.

Should I use Dynamic IP or PPPoE?

If your main router is already providing the Internet connection and automatically assigning IP addresses, Dynamic IP is normally the appropriate choice.

What should I enter for VLAN ID?

If your network does not require VLAN tagging, leave the VLAN ID disabled or blank. If your ISP or network administrator provides a specific VLAN ID, use the value they provide.

Can I use the same WiFi password on both routers?

Yes. In an appropriate Access Point configuration, you can use the same WiFi name and password. However, using the same SSID does not necessarily provide mesh-style roaming.

Conclusion

Using a Tenda router with an existing router through an Ethernet cable can be an effective way to provide additional WiFi coverage.

The exact configuration depends on your Tenda model and firmware. If an Access Point mode is available, it can be used to provide WiFi while keeping devices on the same local network. Alternatively, the Tenda can be configured as a second router using its WAN functionality.

For the Tenda 4G03 Pro example, when using its Ethernet WAN connection, Dynamic IP Address is appropriate when the main router automatically provides an IP address. The VLAN ID should normally remain disabled or blank unless VLAN tagging is specifically required.

Before changing advanced settings, always check the documentation and firmware options for your specific Tenda router model.

Sundar Pichai urges employees to test AI chatbot(Bard) : How Google's Bard stacks up against ChatGPT(AI NEWS)

Google the tech giant, has been facing criticism for its slow response in launching a rival product to the popular AI powered chatbot, ChatGPT. This criticism was further amplified after Google's AI tool, Bard was released in a rush. With mounting AI pressure Google CEO Sundar Pichai urged employees to test the company's new artificial intelligence chat tool for a few hours. In a company wide email Pichai wrote that he understands the moment is " uncomfortably exciting " as the underlying technology is evolving rapidly with so much potential. He further asked employees to dedicate two to four hours of their time to test the company's AI chat tool, Bard.

Pichai also shared that not all products were launched first, but it has not been a hurdle in the company's ability to win. "Some of our most successful products were not first to market. They gained momentum because they solved important user needs and were built on deep technical insights " Pichai wrote in the letter.After the popularity of AI powered chatbot ChatGPT, Google announced its own AI conversational tool, Bard. However, Google Bard is different from Microsoft backed ChatGPT in a few ways. The company is now seeking to differentiate itself in the AI chatbot space.

Pichai acknowledged that this is a long journey for everyone, across the field.He emphasized that the most important thing they can do right now is to focus on building a great product and developing it responsibly.

Google's late entry in launching a web browser Chrome did not stop it from dominating the market. Similarly, before Google launched Android, multiple operating systems were already in place, but Android now dominates the mobile OS market. However the company's launch of Allo instant messaging mobile app could not make inroads due to the popularity of WhatsApp.

Bard is Google's conversational AI chatbot, aimed at enhancing user experience. Google is utilizing its expertise in natural language processing to create a powerful chatbot that can understand complex queries and respond to them accurately. With the increased popularity of ChatGPT,Google aims to build an AI chatbot that solves important user needs and is built on deep technical insights.

As the world continues to evolve technologically, the AI industry is growing rapidly, and Google is one of the key players. With Bard, Google aims to set itself apart from the competition and provide users with an AI chatbot that is unique and highly functional. The company's CEO, Sundar Pichai, is committed to building a great product and developing it responsibly, and has asked employees to contribute to its success through a special company-wide dogfood practice.

Start Learn PHP/MYSQL : How to Do Object Oriented Programming(OOP) in PHP( Easy Explained )

Object-oriented programming(OOP) is a popular programming model used in present time software development. With OOP, programmers can organize code into reusable, modular components, which makes software development more efficient and easier to maintain. PHP, one of the most popular server side scripting languages,supports OOP concepts and provides developers with powerful tools to create robust and scalable applications.

In this article we will take closer look at oops in PHP and explore benefits it offers to developers.We will also discuss essential OOP concepts and how to use them in PHP programming.

What is Object-Oriented Programming.(OOP)?

Object-Oriented Programming is a programming model that focuses on creating software components that can be reused and combined to create complex/big applications.OOP is built around the concept of objects which represent real world entities or concepts. An object is a self contained unit that has properties and methods that define its behaviour.

PHP and OOP:

PHP supports OOP concepts and starting from PHP5 it provides robust support for OOP programming. OOP in PHP enables developers to create complex applications by breaking them down into smaller, reusable components. OOP in PHP allows developers to write more organized and maintainable code which is easier to debug and extend.

Object-Oriented Programming(OOP) in PHP has a large number of methods and keywords that are used to create classes,objects & methods.Here are some of most commonly used Object-Oriented Programming methods and keywords in PHP programming:

Methods:

• __construct():a special method that is automatically called when an object is instantiate.
• __destruct():a special method that is automatically called when an object is destroy.
• __get(): a method that is called when an inaccessible property is accessed.
• __set(): a method that is called when an inaccessible property is set.
• __call(): a method that is called when a not accessible method is called.
• static: a keyword used to define static methods and properties.
• final: a keyword used to stop a class from being sub classed or a method from being overridden.
• abstract: a keyword used to define abstract classes & methods.
• interface: a keyword used to define interfaces.

Keywords:

• class:a keyword used to define a class.
• new:a keyword used to create an object instance of a class.
• extends : a keyword used to define inheritance between classes.
• public :a keyword used to declare a property/method as publicly accessible.
• private -a keyword used to declare a property or method as accessible only within the class that defines it
• protected -a keyword used to declare a property or method as accessible only within the class that defines it and its subclasses
• this -a keyword used to refer to the current object instance within a class method
• self - a keyword used to refer to the current class within a class method
• parent - a keyword used to refer to the parent class within a class method

These are just a few of the many methods & keywords available in OOP in PHP. By understanding and using these methods and keywords effectively, you can create more powerful and efficient object-oriented code.

Essential OOP Concepts:

Classes and Objects:

Classes define the blueprint or structure of an object, while objects are instances of a class. A class is a template that defines the properties and methods of an object, while an object is a concrete realization of a class.

In PHP there are three types of classes and objects: regular classes, abstract classes and interfaces.Let's take a look at each of them and their rules.

1. Regular Classes Regular classes are the most common type of class in PHP and they can be instantiated to create objects.These classes can have properties and methods, which can be accessed using object notation.

Rules:

• Regular classes must have a class keyword followed by a name and a set of curly braces.
• Class names should follow CamelCase naming convention.
• A class must be instantiated before it can be used to create objects.
• Properties and methods must have an access modifier, which determines their visibility.The three access modifiers are public, protected and private.
• A class can inherit from another class using the extends keyword.

Example:

PHP
< pre class="ccontentclss " > <?php class Car { public $make; public $model; public function start() { //code to start the car } private function checkFuel() { //code to check the level of fuel } } ?>
2. Abstract Classes Abstract classes are similar to regular classes but they cannot be instantiated on their own. Instead, they are meant to be extended by other classes. Abstract classes can have abstract methods, which are methods without implementation.These methods must be implemented by any class that extends the abstract class.

Rules:

• Abstract classes must have an abstract keyword before the class keyword.
• An abstract class cannot be instantiated on its own.
• Abstract classes can have abstract methods which are declared without an implementation.
• Any class that extends an abstract class must implement all of its abstract methods.

Example:

PHP
< pre class="ccontentclss " > <?php abstract class Vehicle { public $make; public $model; abstract public function start(); } ?>
3. Interfaces Interfaces are alike to abstract classes but they can only have method signatures and constants.Any class that implements an interface must implement all of its methods. Interfaces are used to define a set of methods that must be implemented by any class that wants to use them.

Rules:

• Interfaces must have an interface keyword followed by a name and a set of curly braces.
• Interfaces can only have method signatures and constants not properties or method implementations.
• Any class that implements an interface must implement all of its methods.

Example:

PHP
< pre class="ccontentclss " > <?php interface Printable { public function print(); } ?>

In summary regular classes, abstract classes and interfaces all have different rules and use cases in PHP. Regular classes are the most common and can be instantiated to create objects while abstract classes and interfaces are used for more specialized cases, such as creating blueprints for other classes or defining a set of methods that must be implemented by other classes.

Full Example of classes and objects in PHP.Imagine we are building a simple website for a library, and we want to create a class for the books that will be displayed on the site.We can create a Book class that will have properties for the title, author, and number of pages.

PHP
< pre class="ccontentclss " > <?php class Book { public $title; public $author; public $pages; } ?>

We can then create object of the BOOK class and set its properties...

PHP
< pre class="ccontentclss " > <?php $book1 = new Book(); $book1->title = "To Kill a Mockingbirds"; $book1->author = "Harry Lee"; $book1->pages = 281; ?>

We can also create additional objects of the BOOK class and set their properties...

PHP
< pre class="ccontentclss " > <?php $book2 = new Book(); $book2->title = "The Great Gat sby"; $book2->author = "F. Scott Fitz gerald"; $book2->pages = 180; $book3 = new Book(); $book3->title = "Pride and Pre judice"; $book3->author = "Jane Aus"; $book3->pages = 279; ?>

We can then display the properties of each object using the echo statement.

PHP
< pre class="ccontentclss " > <?php echo $book1->title; // Output: To Kill a Mockingbird echo $book2->author; // Output: F. Scott Fitzgerald echo $book3->pages; // Output: 279 ?>

We can also define methods with in the Book class to perform various tasks such as calculating the number of pages read per hour.

PHP
< pre class="ccontentclss " > <?php class Book { public $title; public $author; public $pages; public function readPagesPerHour($hours) { return $this->pages / $hours; } } ?>

We can then call method on an object of the BOOK class...

PHP
< pre class="ccontentclss " > <?php $book1 = new Book(); $book1->title = "To Kill a Mockingbird"; $book1->author = "Harper Lee"; $book1->pages = 281; echo $book1->readPagesPerHour(2); // Output: 140.5 ?>

As you can see classes and objects in PHP provide a powerful way to encapsulate data and logic in reusable components. By defining a class, we can create multiple instances of that class (i.e.objects) with their own unique properties and methods.This makes our code more modular and easier to maintain as well as more efficient and scalable.

Encapsulation:

Encapsulation is a mechanism that hides the internal details of an object and exposes only the necessary information. It ensures that the data inside an object is not accessible from outside the object. It is an important concept in Object-Oriented Programming(OOP) that allows you to hide the implementation details of a class from the outside world.This helps to prevent accidental modification of class properties and methods and ensures that they are only accessed and modified in a controlled way. In PHP,encapsulation can be achieved using access modifiers such as public, private and protected.

Public:

Public properties and methods are accessible from anywhere in the code both inside and outside of the class. This means that they can be accessed by objects, functions, and other classes.

Private :

Private properties and methods are only accessible from with in the class. They cannot be accessed by objects functions or other classes outside of the class. This means that the value of a private property can only be set or retrieved by methods within the same class.

Protected :

Protected properties and methods are only accessible from within the class and its subclasses. This means that they cannot be accessed by objects or functions outside of the class but they can be accessed by subclasses that inherit from the class.

Here example of Encapsulation in PHP:

PHP

< pre class="ccontentclss " > <?php class BankAccount { private $balance; public function deposit($amount) { $this->balance += $amount; } public function withdraw($amount) { if ($amount <= $this->balance) { $this->balance -= $amount; } else { echo "Insufficient funds"; } } public function getBalance() { return $this->balance; } } ?>

In this example, we define a Bank Account class with a private property $balance and three methods: deposit(), withdraw()and getBalance(). The deposit() method allows a user to add money to their account, while the withdraw() method allows them to remove money from their account. The getBalance() method allows them to check their current account balance.

Note that the $balance property is marked as private, which means that it can only be accessed within the class itself. This ensures that the balance can only be modified by the deposit() and withdraw() methods, and cannot be accessed or modified directly from outside the class. This helps to prevent accidental modification of the balance and ensures that it is only accessed and modified in a controlled way.

Here an example of how to use the Bank Account class:

PHP

< pre class="ccontentclss " > <?php $account = new BankAccount(); $account->deposit(1000); $account->withdraw(500); echo "Acc Balance: " . $account->getBalance(); ?>

In this example we create a new Bank Account object, deposit 1000 into the account, withdraw 500 from the account, and then print the current balance using the getBalance() method. Note that we can only access the balance using the getBalance() method, and cannot modify it directly.

By encapsulating the balance property and only allowing it to be accessed and modified through controlled methods, we can ensure that the account balance is always accurate and that it cannot be accidentally modified or tampered with.

Inheritance:

Inheritance is a mechanism that enables one class to inherit properties and methods from another class. Inheritance promotes code reuse, and it simplifies the design and maintenance of complex applications.It is a powerful feature in Object-Oriented Programming (OOP) that allows you to create new classes that are based on existing classes, inheriting their properties and methods. In PHP, you can use the extends keyword to create a subclass that inherits from a parent class.

Here example of inheritance in PHP:

PHP
< pre class="ccontentclss " > <?php class Animal { protected $name; protected $color; public function __construct($name, $color) { $this->name = $name; $this->color = $color; } public function eat() { echo "{$this->name} eating..."; } } class Dog extends Animal { public function bark() { echo "{$this->name} barking..."; } } ?>

In this example we define an Animal class with two protected properties ($name and $color) and a eat() method. We then define a Dog class that extends the Animal class, and adds a bark() method.

Note that the Dog class uses the extends keyword to inherit from the Animal class.This means that the Dog class will have access to all of the properties and methods of the Animal class, as well as its own bark() method.

Here example of how to use the Dog class:

PHP
< pre class="ccontentclss " > <?php $dog = new Dog('Fido', 'Brown'); $dog->eat(); // Output: Fido eating... $dog->bark(); // Output: Fido barking... ?>

In this example we create a new DOG object and pass in a name and color to its constructor.We then call its eat() and bark() methods which were inherited from the Animal class and defined in the Dog class respectively.

By using inheritance we can create new classes that are based on existing classes inheriting their properties and methods and adding new functionality. This allows us to write more efficient and reusable code and makes it easier to organize and maintain our programs

Polymorphism:

Polymorphism is the ability of an object to take on different forms or behaviors. In PHP, polymorphism is achieved through method overriding and method overloading.It is an important concept in Object-Oriented Programming (OOP) that allows objects of different classes to be treated as if they were the same type. This is achieved by using inheritance and method overriding, which allows a subclass to provide its own implementation of a method that is already defined in its parent class. In PHP, polymorphism can be achieved using the extends keyword and the override keyword.

Here example of polymorphism in PHP:

PHP
< pre class="ccontentclss " > <?php class Shape { public function getArea() { return 0; } } class Circle extends Shape { private $radius; public function __construct($radius) { $this->radius = $radius; } public function getArea() { return 3.14 * $this->radius * $this->radius; } } class Square extends Shape { private $length; public function __construct($length){ $this->length = $length; } public function getArea() { return $this->length * $this->length; } } ?>

In this example we define a Shape class with a getArea() method that returns 0.We then define two subclasses: Circle and Square, both of which extend the Shape class and provide their own implementation of the getArea() method.

Note that the getArea() method is defined in the Shape class and overridden in the Circle and Square classes. This allows objects of the Circle and Square classes to be treated as if they were objects of the Shape class because they share the same method signature.

Here example of how to use the Shape, Circle, and Square classes:

PHP
< pre class="ccontentclss " > <?php $shapes = array( new Circle(5), new Square(4), new Circle(3) ); foreach ($shapes as $shape){ echo "Area: " . $shape->getArea() . "<br>"; } ?>

In this example we create an array of Shape objects that contains two Circle objects and one Square object. We then iterate over the array and call the getArea() method on each object which will call the appropriate implementation of the method in each subclass.

By using polymorphism we can write more flexible and extensible code that can be easily adapted to different situations. This allows us to write code that is more maintainable, reusable and efficient and makes it easier to add new functionality to our programs.

Abstraction:

Abstraction is a mechanism that allows developers to create generalized models of realworld entities / concepts. It helps to reduce complexity and increase the reusability of code.It is an important concept in Object-Oriented Programming (OOP) that allows us to hide the implementation details of a class from its users, while still providing a clear and concise interface for interacting with that class. In PHP we can achieve abstraction by using abstract classes and abstract methods.

Here example of abstraction in PHP:

PHP
< pre class="ccontentclss " > <?php abstract class Shape { protected $color; public function __construct($color) { $this->color = $color; } public function getColor() { return $this->color; } abstract public function getArea(); } class Circle extends Shape { private $radius; public function __construct($color, $radius) { parent::__construct($color); $this->radius = $radius; } public function getArea() { return 3.14 * $this->radius * $this->radius; } } class Square extends Shape { private $length; public function __construct($color, $length) { parent::__construct($color); $this->length = $length; } public function getArea() { return $this->length * $this->length; } } ?>

In this example we define a Shape class with a getArea() method that returns 0. We then define two subclasses: Circle and Square, both of which extend the Shape class and provide their own implementation of the getArea() method.

Note that the getArea() method is defined in the Shape class and overridden in the Circle and Square classes. This allows objects of the Circle and Square classes to be treated as if they were objects of the Shape class because they share the same method signature.

Here example of how to use the Shape, Circle and Square classes:

PHP
< pre class="ccontentclss " > <?php $shapes = array( new Circle(5), new Square(4), new Circle(3) ); foreach ($shapes as $shape) { echo "Area : " . $shape->getArea() . "
"; } ?>

In this example We create an array of Shape objects that contains two Circle objects and one Square object.We then iterate over the array and call the getArea() method on each object which will call the appropriate implementation of the method in each subclass.

By using polymorphism we can write more flexible and extensible code that can be easily adapted to different situations.This allows us to write code that is more maintainable, reusable and efficient and makes it easier to add new functionality to our programs.

Benefits of OOP in PHP:

1. Reusability :OOP in PHP enables developers to write reusable code, which reduces development time and increases efficiency.

2. Modularity: OOP in PHP allows developers to break down complex applications into smaller manageable components.This improves the organization of code and makes it easier to maintain and debug.

3. Extensibility: OOP in PHP promotes the use of inheritance and polymorphism which allows developers to extend the functionality of existing code without modifying the original code.

4. Security: O O P in PHP enables developers to implement secure coding practices such as encapsulation and data hiding which helps to protect sensitive data from unauthorized access.

OOP in PHP is a powerful programming paradigm that enables developers to create scalable, efficient and maintainable applications. The essential OOP concepts in PHP including classes and objects, encapsulation, inheritance, polymorphism and abstraction, make it possible to create reusable, modular and secure code. By understanding the benefits of OOP in PHP developers can write better quality code that is easier to maintain and extend.

If you are interested in building web applications and working with databases but do not know where to start you have come to the right place. In our previous articles we have covered topics likePHP and MySQL setup for Windows and Linux OS. Today we will dive into the basics of PHP. As a powerful and versatile programming language, PHP is widely used for developing dynamic web applications, handling files and connecting to databases.By mastering its fundamentals you can take your web development skills to the next level.

In this guide we will focus specifically on the basics of PHP web development and database connectivity. From variables and data types to operators, control structures and functions we will cover everything you need to know to get started with PHP.With real world examples and best practices we will guide you through the process of connecting PHP to a database and working with common database operations like reading, writing and updating data.

Whether you are a beginner or have some experience with other programming languages this guide will provide a solid foundation for building your skills in PHP and developing your own web applications.So let's Get started and learn the basics of web development and database connectivity in PHP to become a proficient web developer .

Here are some of the basics of PHP:

1. Syntax: PHP code is typically embedded within HTML, using opening and closing tags respectively. PHP statements end with a semicolon (;).
2. Variables: In PHP you can define variables using the $ symbol, followed by the variable name. For example, $name = "John"; assigns the value "John" to the variable $name.
3. Data Types: PHP has various data types, including strings, integers, floats, booleans, arrays and objects.
4. Operators: PHP has various operators including arithmetic (+, -, *, /, %), assignment (=), comparison (==, !=, >, <, >=, <=), and logical (&&, ||, !).
5. Control Structures: PHP has various control structures, including if-else statements, switch statements, while and do-while loops ,for loops and foreach loops.
6. Functions: PHP allows you to define and call functions. Functions are used to perform specific tasks and can be reused throughout your code.
7. Forms: PHP is commonly used in web development to process data submitted through HTML forms.

1.Syntax:

PHP is a server side scripting language which means that the code is executed on the server before the resulting HTML is sent to the client's browser. PHP code is typically embedded within HTML using opening and closing tags respectively.Here is an example of PHP code that prints "Hello world!" to the screen:

PHP

 <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 echo "Hello world!";  
 ?>  
   
 </body>  
  </html> 

In Example echo statement is used to print the text "Hello world !" to the screen.

get started with running PHP code on your PC the first step is to run XAMPP controller .This will allow you to run PHP code on your computer/PC. Once XAMPP is running navigate to the C > xampp > htdocs folder on your PC. In this folder create a new folder called "test".Next create a new file in this folder called "index.php". You can open this file in a plain text editor like notepad or you can download a more advanced editor like Sublime & Visual Studio .

After opening the "index.php" file in your text editor copy the PHP code from above and paste it into the file. Save the file close the editor. You re now ready to run your first PHP Code .

To do this open your web browser (such as Google Chrome/ Internet Explorer)and enter the following URL in the address bar:"localhost/test/index.php". This will run the PHP code and display the message "Hello world!" in your web browser .

Congratulations you have successfully Run your first PHP code on your PC/Computer.With this basic setup you can now begin to learn more about PHP and Start building your own web applications .

2.Variables:

In PHP variables re used to store values.Variables can be assigned a value using the $ symbol followed by the variable name . Example :

PHP

 <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $name = "John";  
 $age = 30;  
 $height = 1.75;  
 $is_student = true;  
 ?>  
     
 <?php echo $name; ?><br>  
 <?php echo $age; ?><br>  
 <?php echo $height; ?><br>  
 <?php echo $is_student; ?>  
   
  
 </body>  
 </html>   

In this example four variables are defined: $name, $age, $height and $is_student. The variable $name is assigned the value "John" $age is assigned the value 30 $height is assigned the value 1.75 and $is_student is assigned the value true. Note that PHP is a loosely typed language, which means that the data type of a variable is determined automatically based on the value assigned to it.

3.Data Types:

PHP has several data types including:

• Strings: a sequence of characters enclosed in quotes. Example : "Hello world!"
• Integers: whole numbers without a decimal point. Example: 42
• Floats: numbers with a decimal point. Example: 3.14
• Booleans: true or false. Example: true
• Arrays: a collection of values indexed by a key. Example: $colors = array("red", "green", "blue");
• Objects: a complex data type that represents a realworld object.

Example:

PHP

 <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $name = " John ";  
 $age = 30;  
 ?>  
     
 <?php echo " Hello my name is $name and I m $age years old . "; ?>  
   
   
   
 </body>  
 </html>  

In the above code , we define two variables using PHP.$name is a string datatype and is assigned the value "John" while $age is an integer datatype and is assigned the value 30. Using the echo statement we print a greeting to the screen that includes the values of these variables. The output of the code will be "Hello , my name is John and I am 30 years old". This simple example demonstrates how to define variables and output their values using PHP.

4.Operators:

PHP has several operators including:

1.Arithmetic operators: used to perform mathematical operations , such as addition (+), subtraction (-), multiplication (*), division (/) and modulus (%) .

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
 <?php  
 $x = 10;  
 $y = 3;  
 echo $x + $y;    //Outputs 13  
 echo $x - $y; // Outputs 7  
 echo $x * $y; //Outputs 30  
 echo $x / $y; // Outputs 3.3333333333333  
 echo $x % $y; // Outputs 1  
 ?>  
   
   
   
 
 </body>  
 </html>  

2.Assignment operators : used to assign a value to a variable . Example:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $x = 10;
 $y = 3;
 $x += $y;  // equivalent to  $x = $x + $y;
 $x -= $y;   //  equivalent to $x = $x - $y;
 $x *= $y; // equivalent to $x = $x * $y;
 $x /= $y; //  equivalent to $x = $x / $y;
 $x %= $y; // equivalent to $x = $x % $y;
 ?>  
   
   
   
   
 </body>  
 </html>  

3.Comparison operators : used to compare two values . Example:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
  $x = 10;  
  $y = 3;  
  var_dump($x == $y); // Outputs bool(false)  
  var_dump($x != $y); // Outputs bool(true)  
  var_dump($x > $y); // Outputs bool(true)  
  var_dump($x < $y); // Outputs bool(false)  
  var_dump($x >= $y); // Outputs bool(true)  
  var_dump($x <= $y); // Outputs bool(false)  
 ?>  
   
   
   
   
 </body>  
 </html>  

4.Logical operators : used to combine two or more conditions . Example:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
  $x = 10;  
 $y = 3;  
 $z = 5;  
 var_dump($x > $y && $x > $z); // Outputs bool(true)  
 var_dump($x > $y || $x < $z); // Outputs bool(true)  
 var_dump(!($x > $y)); // Outputs bool(false)   
 ?>  
   
   
   
   
 </body>  
 </html>  

5.Control Structures:

Control Structures In PHP re Used to execute code based on certain conditions .

If-else statements : used to execute code if a certain condition is true or execute a different code if the condition is false. Example:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $x = 10;
$y = 3;
if ($x > $y) {
  echo "x is greater than y";
} else {
  echo "x is less than or equal to y";
}  
//Outputs x is greater than y
 ?>  
   
   
   
   
 </body>  
 </html>  

Switch statements : used to execute different code blocks based on the value of a variable . Example:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$day = "Monday";
switch ($day) {
  case "Monday":
    echo "Today is monday";
    break;
  case "Tuesday":
    echo "Today is tuesday";
    break;
  case "Wednesday":
    echo "Today is wednesday";
    break;
  default:
    echo "Today is not monday, tuesday or wednesday";
} 
//Outputs Today is monday
 ?>  
   
   
   
   
 </body>  
 </html>  

Loops: used to execute a block of code multiple times . Here are some examples:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
<?php  
 // While loop  
 $i = 1;  
 while ($i <= 10) {  
  echo $i;  
  $i++;  
 }  
 ?>  //Outputs 12345678910
 <br> <?php  
 // Do-while loop  
 $i = 1;  
 do {  
  echo $i;  
  $i++;  
 } while ($i <= 10);  
   
 // For loop  
 for ($i = 1; $i <= 10; $i++) {  
  echo $i;  
 }  
 ?>  //Outputs 1234567891012345678910
 <br><?php  
 // Foreach loop (used to loop through arrays)  
 $colors = array("Red", "Green", "Blue");  
 foreach ($colors as $color) {  
  echo $color;  
 }  
 ?>  //Outputs RedGreenBlue
    


   
   
   
   
 </body>  
 </html>  

6.Functions:

Functions in PHP are used to perform specific tasks and can be reused throughout your code. Here 's an example of a function that calculates the sum of two numbers :

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
function sum($x, $y) {
  $result = $x + $y;
  return $result;
}

echo sum(2, 3); 

 ?>  // Outputs 5
   
   
   
   
 </body>  
 </html>  

In this example a function called 'sum ' is defined that takes two parameters $x and $y calculates their sum and returns the result using the return statement. The function is then called with the arguments 2 and 3 and the result is printed using the echo statement.

Functions can also have default parameter values which are used if no value is passed in for that parameter:

PHP

 <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
function sayHello($name = "World") {
  echo "Hello, $name!";
}

sayHello(); 
sayHello("John"); 

 ?>  // Outputs "Hello World!" 
 // Outputs "Hello John!" 
   
   
   
   
 </body>  
 </html>  

In this example a function called sayHello is defined that takes an optional parameter $name with a default value of "World" . If a value is passed in for $name that value is used , otherwise the default value is used. The function is then called twice once with no argument and once with the argument "John" , and the output is printed using the echo statement.

7.Arrays:

Arrays in PHP are used to store multiple values in a single variable. Here 's an example of an array:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$colors = array("red", "green", "blue");
echo $colors[0]; // Outputs "red"
echo $colors[1]; // Outputs "green"
echo $colors[2]; // Outputs "blue"

 ?>  
   
   
   
   
 </body>  
 </html>  

In this example an array called $colors is defined that contains three elements . The elements are accessed using their index , which starts at 0.

Arrays can also be created using the array function :

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$ages = array("Peter" => 32, "John" => 28, "Mary" => 45);
echo $ages["John"]; // Outputs 28

 ?>  
   
   
   
   
 </body>  
 </html>  

In this example an array called $ages is defined using key-value pairs . The elements are accessed using their key which is a string .

Arrays can be looped through using the foreach loop :

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$colors = array("red", "green", "blue");
foreach ($colors as $color) {
  echo $color;
}
// Outputs RedGreenBlue
 ?>  
   
   
   
   
 </body>  
 </html>  

In this example the array $colors is looped through using the foreach loop and each element is printed using the echo statement.

8.File Handling:

File handling in PHP is used to read and write files on a server . The fopen function is used to open a file and returns a file pointer that is used to access the file. Here 's an example of reading a file: Create a new file and name it "example.txt".Type "Hello World My name is Jhon" into the file and save the file .

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$file = fopen("example.txt", "r");
if ($file) {
  while (($line = fgets($file)) !== false) {
    echo $line;
  }
  fclose($file);
}
// Outputs Hello World My name  is Jhon
 ?>  
   
   
   
   
 </body>  
 </html>  

In this example the fopen function is used to open a file called example.txt in read mode . The while loop is used to read each line of the file using the fgets function and output it using the echo statement. Finally the fclose function is used to close the file .

writing to a file is also possible Using the fopen function in write mode :

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
$file = fopen("example.txt", "w");
fwrite($file, "Hello World!");
fclose($file);
 ?>  
   
   
   
   
 </body>  
 </html>  

In this example, the fopen function is used to open a file called example.txt in write mode. The fwrite function is used to write the string "Hello World!" to the file, and the fclose function is used to close the file.

9. Database Connectivity:

PHP is often used for web development, and it 's common to interact with databases to store and retrieve data. PHP provides several extensions to interact with databases including MySQL and PostgreSQL.

In a previous post about MySQL, we discussed how to create a database and table. In this post we will provide a summary of those steps and explain how to create a database using phpMyAdmin .

In this post we will explain how to create a database using phpMyAdmin which is a popular webbased tool for managing MySQL databases. With phpMyAdmin you can easily create and manage databases , tables and other database objects.

You can create a new database by following these Steps:

1. Click on the "New" button in the left hand navigation menu to create a new database.
2. Enter a name for your database in the "Create database" form.You can choose any name you like but it ' s a good idea to choose something descriptive and easy to remember.
3. Select the default collation for your database. This specifies the character set and sorting order that should be used for text data in your database. In most cases , you can leave this set to the default value of "utf8_general_ci".
4. Click the "Create" button to create your new database.

Once you have created your database , you can start creating tables by following these steps:

1. Click on the name of the database you just created to enter it.
2. Click on the "New" button in the left hand navigation menu to create a new table.
3. Enter a name for your table in the "Create table" form. Again , it 's a good idea to choose a descriptive name that reflects the purpose of your table.
4. Enter the number of Columns you want your table to have.Each column represents a different Type of data that you want to store in the table.
5. For each column, enter a name and select a data type. The data type determines the kind of data that can be stored in the column. For example , you might use an "int" data type for numeric values or a "varchar" data type for text strings.
6. You can also specify additional options for each column, such as whether it should be a primary key (which uniquely identifies each row in the table), or whether it should have a default value or be set to auto-increment.
7. Once you have defined all of your columns and their options, click the "Save" button to create your new table.

That's it! You have now created a new database and table using phpMyAdmin. From here, you can start populating your table with data, running queries and managing your database in a variety of other ways.

To create a table named "users" with three columns - "id", "name" and "email" - using phpMyAdmin, you can follow these steps:

1. Open phpMyAdmin and select the database where you want to create the "users" table.You can select the database by clicking on its name in the left-hand sidebar.

2. Click on the "Structure" tab at the top of the page to create a new table.

3. In the "Create table" section, enter "users" in the "Table name" field.

4. Under "Number of columns" , enter "3".

5. In the first row of the "Column name" column, enter "id".

6. In the "Type" column for the "id" column select "INT" for integer.

7. Check the "A.I." (Auto Increment) checkbox to make the "id" column an autoincrementing field.

8. In the "Attributes" section for the "id" column, select "Primary" to make it the primary key of the table.

9. Repeat steps 5-8 for the "name" and "email" columns.

10. Click on the "Save" button at the bottom of the page to create the "users" table with the specified columns.

That 's it! You have now successfully created a new table named "users" with three columns using phpMyAdmin. You can now start populating the table with data by using the "Insert" tab in phpMyAdmin or by using SQL statements to insert data directly into the table.

Insert query

To insert data into the "users" table using SQL queries in PHP You can use The following code :

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
// Insert data into the table
$sql = "INSERT INTO users (name, email) VALUES ('John', 'john@example.com')";
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "
" . $conn->error;
}
   
 // Close connection  
 $conn->close();  
 ?>    
   
   
   //Outputs new record created successfully
   
 </body>  
 </html>  

This code creates a new connection to your MySQL database using the connection variables (servername, username, password, dbname), and then inserts a new record into the "users" table with the values "John " for the "name" column and "john@example.com" for the "email" column.

SELECT query

Here 's an example of connecting to a MySQL database and executing a query:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
 // Execute query  
 $sql = "SELECT * FROM users";  
 $result = $conn->query($sql);  
   
 // Output results  
 if ($result->num_rows > 0) {  
  while ($row = $result->fetch_assoc()) {  
   echo "Name: " . $row["name"] . " - Email: " . $row["email"];  
  }  
 } else {  
  echo "0 results";  
 }  
   
 // Close connection  
 $conn->close();  
 ?>    
   
     //Outputs Name: John - Email: john@example.com
   
   
 </body>  
 </html>  

In this Example, a connection to a MySQL database is established using the mysqli extension. The connect_error property is used to check if the connection was successful.The query method is used to execute a SQL query, and the fetch_assoc method is used to retrieve each row of the result set. Finally , the close method is used to Close the connection.

UPDATE query

To update an existing record in the "users" table using an SQL query in PHP you can use the following code as an example:

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
 // Update record in the table
$sql = "UPDATE users SET name='Jane Ross', email='jane.ross@example.com' WHERE id=1";
if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}
   
 // Close connection  
 $conn->close();  
 ?>    
   
     //Outputs record updated successfully
   
   
 </body>  
 </html>  

In this Example , the code connects to the MySQL database using the connection variables (servername, username, password , dbname) and then updates the record with an "id" value of 1 in the "users" table to set the "name" to "Jane Ross" and The "email" to "jane.ross@example.com" .

You can modify the sql query to update different records in the table with different values.You can use various SQL operators and conditions to specify which records you want to update. For Example , you can use the WHERE clause to Specify a condition that must be met for the record to be updated .

DELETE query

To delete a record from the "users" table using an SQL query in PHP you can use the following code as an example :

PHP

  <!DOCTYPE html>  
 <html>  
 <body>  
   
 <?php  
 $servername = "localhost";  
 $username = "username";  
 $password = "";  
 $dbname = "myDataB";  
   
 // Create connection  
 $conn = new mysqli($servername, $username, $password, $dbname);  
   
 // Check connection  
 if ($conn->connect_error) {  
  die("Connection failed: " . $conn->connect_error);  
 }  
   
 // Delete record from the table
$sql = "DELETE FROM users WHERE id=1";
if ($conn->query($sql) === TRUE) {
    echo "Record deleted successfully";
} else {
    echo "Error deleting record: " . $conn->error;
}
 // Close connection  
 $conn->close();  
 ?>    
   
     //Outputs record deleted successfully
   
   
 </body>  
 </html>  

In this Example , the code connects to the MySQL database using the connection variables (servername, username, password , dbname), and then deletes the record with an "id" value of 1 from the "users" table.

You can modify the SQL query to delete different records from the table based on different conditions. For example you can use the WHERE clause to specify a condition that must be met for the record to be deleted .
