Can anyone help me how to solve it? I already set execution time but still not working: ini_set('max_execution_time', 0); Here is my code

public static function compress($source, $destination)
{
  ini_set('max_execution_time', 0);
  Tinify\setKey(env('API_KEY'));
  Tinify\fromFile($source)->toFile($destination);
