An article explaining how thinkphp sets up the background configuration file

ThinkPHP is a very popular PHP framework, which provides very complete backend management system functions. In the backend management system, configuration is a very important part because it determines the behavior of the website and the running mode of the application.

In ThinkPHP, you can create a custom configuration file through the create() method. For example, we can create a file named config in the config directory. php file, used to store our website configuration. In this file, we can set basic information such as website name, keywords, description, etc.

$config = [

// 网站名称
'site_name' => 'xxx',
// 网站关键词
'site_keywords' => 'xxx',
// 网站描述
'site_description' => 'xxx',

];

In thinkphp, we can pass config() Method to load custom configuration files, as well as system default configuration files. This method can be called anywhere to obtain the corresponding configuration information. For example, we can get the website name in the following way:

$config = config('site_name');

If you want to get multiple configuration information, you can use an array to get it, as follows Shown:

$config = config(['site_name', 'site_keywords', 'site_description']);

3. Modify the configuration file

thinkphp provides the config() method, which can modify the loaded configuration file at runtime. For example, we can change the website name to 'yyy' under certain circumstances, the code is as follows:

config('site_name', 'yyy');

4. Production configuration Item

'db_user' => 'root',
'db_pwd' => 'root',
'db_host' => '127.0.0.1',

];
