When using the ThinkPHP5 framework, we usually need to read some configuration information in the application, such as database connection information, cache information, etc. In the ThinkPHP5 framework, all configuration files are stored in the config directory. Next, this article will share how to use the ThinkPHP5 framework to read configuration files.

  1. Naming of configuration files

In the ThinkPHP5 framework, all configuration files are saved in the config directory with the .php file extension. The naming rule of the configuration file is: application configuration-controller configuration-method configuration.php, such as:

  • Application configuration file name: app.php
  • Controller configuration file name: index.php
  • Method configuration file name: hello.php

In the application, we can read the application configuration file through the following code:

$app_config = config('app');
  1. Read application configuration file

In the application, we can read the application configuration file through the config function, whose parameter is the configuration file name. For example, if we need to read the contents of the app.php configuration file, we can use the following code:

$app_config = config('app');

The sample code to read the application configuration file is as follows:

<?php
namespace app\index\controller;

use think\Controller;

class Index extends Controller
{
    public function index()
    {
        $app_config = config(&#39;app&#39;);
        dump($app_config);
    }
}
  1. Read Controller configuration file

In the controller, we can read the controller configuration file through $this->config. The name of the controller configuration file is: controllername.php, such as:

class Index extends Controller
{
    public function index()
    {
        $controller_config = $this->config;
        dump($controller_config);
    }
}

The sample code for reading the controller configuration file is as follows:

<?php
namespace app\index\controller;

use think\Controller;

class Index extends Controller
{
    public function index()
    {
        $controller_config = $this->config;
        dump($controller_config);
    }
}
  1. Reading method configuration file

In the method, we can read the method configuration file through the config function. The name of the method configuration file is: method name.php, such as:

class Index extends Controller
{
    public function hello()
    {
        $action_config = config('hello');
        dump($action_config);
    }
}

The sample code for reading the method configuration file is as follows:

<?php
namespace app\index\controller;

use think\Controller;

class Index extends Controller
{
    public function hello()
    {
        $action_config = config('hello');
        dump($action_config);
    }
}
  1. Reading other files

In addition to app.php, controller configuration files and method configuration files, we can also read custom configuration files through the config function. Customized configuration files must have a .php file extension and be placed in the config directory. The sample code for reading a custom configuration file is as follows:

<?php
namespace app\index\controller;

use think\Controller;

class Index extends Controller
{
    public function index()
    {
        $custom_config = config('custom');
        dump($custom_config);
    }
}

Summary: It is very simple to use the ThinkPHP5 framework to read configuration files. Through the introduction of this article, we have learned how to read application configuration files, controller configuration files, Method configuration files and custom configuration files. Developers can choose different ways to read configuration files based on actual needs.
