Fix configuration does not take effect in real time

The array_diff difference value is obtained from the first parameter. Therefore, the modification of the configuration file needs to wait for the next time to take effect.

$ php -r "var_dump(array_diff(['a' => 1, 'b' => 2], ['a' => 2, 'c' => 2]));"
array(1) {
  ["a"]=>
  int(1)
}
