FuelPHP is an excellent PHP framework that provides developers with many convenient functions and tools, including ORM (Object Relational Mapping), template engine, router, input and output validation, security, etc. In this article, we will introduce how to use the FuelPHP framework.

Installing FuelPHP

Before you start using FuelPHP, you need to install it. FuelPHP officially provides two ways to install:

(1) Use composer to install

Use composer to quickly install FuelPHP. Just run the following command on the command line:

composer create-project fuelphp/fuel myapp

Copy after login

where myapp can be replaced with your project name.

(2) Manual installation

The manual installation method is a little more troublesome. First, you need to go to the FuelPHP official website to download the latest version of the framework file. Then extract the downloaded file into your project directory.

Configuring FuelPHP

Before using FuelPHP, some configuration is required. By default, FuelPHP will provide a config.php file in the /fuel/app/config directory, which contains many options that need to be configured. Such as database connection, default time zone, logging, etc. You can modify the configuration items in this file to suit your project needs.

Create a controller

The controller is a component in the FuelPHP framework that is responsible for processing user requests. We can create a new controller in the /fuel/app/classes/controller directory. Here is a simple example:

<?php
class Controller_Welcome extends Controller
{
  public function action_index()
  {
    return Response::forge(View::forge('welcome'));
  }
}

Copy after login

In the above example, we created a controller named Welcome, which has a controller named action_index method. This method will be called when the user visits index.php/welcome. In this method, we use View to render a view page named welcome. This page should be located in the /fuel/app/views directory.

Create Views

In FuelPHP, you can use views to display your HTML pages. Create a new view in the /fuel/app/views directory. Here is a simple example:

<!DOCTYPE html>
<html>
<head>
  <title>Welcome</title>
</head>
<body>
  <h1>Welcome to my website!</h1>
</body>
</html>

Copy after login

In the above example, we create a view page called welcome, which contains a h1 tag, and Welcome message is displayed.

Router

Router is the component in the FuelPHP framework that is used to map user requests to controllers and action methods. By default, FuelPHP will automatically route user requests based on the controller name and action name in the URL. For example, /index.php/welcome will be mapped to the index method of the Welcome controller. If you want to add custom routing rules, you can define them in the /fuel/app/config/routes.php file.

Run the FuelPHP application

After completing the above steps, you are ready to run the FuelPHP application. Open the command terminal, switch to your project directory, and run the following command:

php oil server

Copy after login

This command will start a web server on your local computer and listen to port number 8000. In your web browser, visit http://localhost:8000 and you should see the Welcome to my website! welcome message.

Summary

The above is the basic process of using the FuelPHP framework. To master it, you need to learn and understand step by step what each component does and how to use it. FuelPHP framework is a very powerful and flexible PHP framework that helps you build web applications faster and more efficiently.
