In fact, PHP has its own dedicated error handling API. When a problem occurs in the program, the specified function can be automatically called. Yii2 takes advantage of this. When it starts, it uses PHP's built-in set_error_handler to register its own error processing and turn off PHP's own error display.

Yii2 error registration mechanism

The following variables will control whether to enable error processing. The default is on. You can turn off the error log by setting the variable value

# \yii\BaseYii.php
/**

 */
 defined('YII_ENABLE_ERROR_HANDLER') or define('YII_ENABLE_ERROR_HANDLER', true);
