How to modify the configuration of thinkphp

ThinkPHP is an MVC framework developed based on PHP language. It is easy to use, flexible and efficient in development, and is widely used in Web application development. When using ThinkPHP, sometimes we need to modify some configurations to meet project needs. This article will introduce how to modify ThinkPHP configuration.

1. Introduction to configuration files

The configuration file of ThinkPHP is stored in the config directory of the application, and the configuration file can be customized. Commonly used configuration files include the following:

1. config.php: Application configuration file, including general application configuration, such as application name, default time zone, routing configuration, cache configuration, etc.;
2. database.php: Database configuration file, including regular database configuration, such as master-slave database configuration, SQL log records, data table prefix, etc.;
3. cache.php: Cache configuration file, including regular cache configuration, such as File cache, Redis cache, etc.;
4. session.php: session configuration file, including session type, driver, expiration time, etc.

Taking config.php as an example, the default settings for this configuration file are as follows:

return [
    // 应用名称
    'app_name'       => 'ThinkPHP',
    // 应用地址
    'app_host'       => '',
    // 应用调试模式
    'app_debug'      => false,
    // 应用Trace
    'app_trace'      => false,
    // 应用模式状态
    'app_status'     => '',
    // 是否支持多模块
    'app_multi_module'          => true,
    // 入口自动绑定模块
    'auto_bind_module'          => false,
    // 注册的根命名空间
    'root_namespace'            => [],
    // 默认输出类型
    'default_return_type'       => 'html',
    // 默认AJAX 数据返回格式,可选json xml ...
    'default_ajax_return'       => 'json',
    // 默认 JSONP 控制器请求变量
    'var_jsonp_handler'         => 'callback',
    // 默认时区
    'default_timezone'          => 'Asia/Shanghai',
];

2. Modify the configuration file

1. Directly modify the configuration file

The simplest way is to modify the corresponding parameter values ​​directly in the configuration file. Let’s take modifying the session expiration time as an example, as follows:

return [
    // session配置
    'session'       => [
        'prefix'         => 'think',
        'type'           => '',
        'auto_start'     => true,
        'expire'         => 3600,  //修改该项即可
        'use_trans_sid'   => false,
        'var_session_id' => 'session_id',
    ],
];

When using this configuration in an application, you can use the config() function to obtain the corresponding configuration parameters, as follows:

// 获取session过期时间
$expire = config('session.expire');

2. Defined in the .env file

In addition to directly modifying the configuration file, ThinkPHP also provides an easy-to-manage method: defining configuration parameters in the .env file. Parameters defined in the .env file will be automatically loaded into the application's configuration file, overriding the default values ​​of parameters with the same name.

.env file is located in the application root directory by default, as follows:

# 应用名称
APP_NAME=thinkphp
# 整体调试模式
APP_DEBUG=true
# 数据库类型
DATABASE_TYPE=mysql
# 数据库主机地址
DATABASE_HOST=127.0.0.1
# 数据库端口
DATABASE_PORT=3306
# 数据库名
DATABASE_NAME=test
# 数据库用户名
DATABASE_USER=root
# 数据库密码
DATABASE_PASSWORD='123456'

When used, call the config() function to obtain the corresponding configuration parameters, as follows:

// 获取数据库类型
$type = config('database.type');

This method can Conveniently configure the environment, and the configurations are different in different environments, making it more flexible.

3. Summary

This article introduces how to modify the configuration file of ThinkPHP, including directly modifying the configuration file and defining configuration parameters in the .env file. In actual development, we can modify the corresponding configuration files according to project needs to achieve better application effects. At the same time, we can also adopt different configuration methods according to different environments.
