thinkphp configuration file modification

When using the ThinkPHP framework to develop PHP applications, configuration files often need to be modified to meet business needs. This article will introduce in detail how to modify the ThinkPHP configuration file.

1. Find the configuration file

ThinkPHP’s configuration file is usually stored in config.php in the application directory under the root directory of the project file. There may also be other configuration files such as database.php, but the names and locations of these files may vary depending on the habits of individual or company developers.

2. Open the configuration file

By opening this file, we can see that it contains a large amount of configuration information, which is divided into different modules according to different functions. , such as database, routing, cache, log, etc.

For a specified configuration item, you can find the corresponding configuration item and modify its value as usual. For example:

return [

    // 数据库配置
    'database' => [
        'type'        => 'mysql',
        'hostname'    => 'localhost',
        'database'    => 'test',
        'username'    => 'root',
        'password'    => '123456',
        'hostport'    => '3306',
        'charset'     => 'utf8', 
        'prefix'      => '',
        'debug'       => true,
        'deploy'      => 0,
        'rw_separate' => false,
        'master_num'  => 1,
        'slave_no'    => '',
        'fields_strict' => true,
        'resultset_type' => 'array',
        'auto_timestamp' => false,
        'sql_explain' => false,
    ],

    // 路由配置
    'route' => [
        'default_controller'    => 'Index',
        'default_action'        => 'index',
        'default_module'        => 'index',
        'url_html_suffix'       => 'html',
        'url_common_param'      => true, 
        'url_route_on'          => true, 
        'route_complete_match'  => false,
        'url_route_must'        => false,
        'url_domain_deploy'     => false,
        'url_domain_root'       => '', 
        'url_convert'           => false, 
        'url_controller_layer'  => 'controller',
        'var_controller'        => 'c',
        'var_action'            => 'a',
    ],

    // 缓存配置
    'cache' => [
        'type'   => 'File',
        'expire' => 0,
        'prefix' => '',
        'path'   => '',
        'host'   => '',
        'port'   => '',
        'password' => '',
        'select' => 0,
        'persistent' => false,
        'timeout' => 0,
        'persistent_id' => '',
    ],

    // 日志配置
    'log' => [
        'type' => 'File',
        'path' => LOG_PATH,
        'level' => ['error'],
    ],

    // 其他配置...
];

For example, if we want to change the database password to 654321, we only need to modify it in the corresponding configuration item:

'database' => [ 
    'type'        => 'mysql',
    'hostname'    => 'localhost',
    'database'    => 'test',
    'username'    => 'root',
    'password'    => '654321', // 将password值修改为新密码
    'hostport'    => '3306',
    'charset'     => 'utf8', 
    'prefix'      => '',
    'debug'       => true,
    'deploy'      => 0,
    'rw_separate' => false,
    'master_num'  => 1,
    'slave_no'    => '',
    'fields_strict' => true,
    'resultset_type' => 'array',
    'auto_timestamp' => false,
    'sql_explain' => false,
],

3. Save changes

After modification, just save it directly.

4. Test modification

To ensure that the modification takes effect, we can try to read the modified configuration value in the application. For example, in a controller, you can use the following code to read the user name and password in the database configuration file:

<?php
namespace appindexcontroller;

class Test
{
    public function index()
    {
        $config = config('database'); // 获取数据库配置信息
        echo '用户名：'. $config['username'] .'<br>';
        echo '密码：'. $config['password'] .'<br>';
    }
}

Then access the method of the controller in the browser, and you can see the output user name and password. has been modified to the new value.

By modifying the ThinkPHP configuration file, we can quickly adjust various configuration parameters of the application to better adapt to different business needs. In the actual development process, we should select appropriate configuration parameters and modify them according to the specific situation to give full play to the advantages of the framework.
