Question

In the following code I call a class with call_user_func().

if(file_exists(\'controller/\' . $this->controller . \'.controller.php\')) {
             


        

Answer 1

You can use the PHP function method_exists():

if (method_exists('ClassName', 'method_name'))
call_user_func(etc...);

or also:

if (method_exists($class_instance, 'method_name'))
call_user_func(etc...);
