Question

Is there such a thing?

Some kind of a magic function that allows you to change stuff before the undefined function call error gets thrown?

Like __call, but for normal functions 🙂

Answer 1

I would do the cheking BEFORE calling the method like this:

$obj = new Foo();
$method = "myMethod";

if(is_callable(array($obj, $method)){
    $obj->$method();
}else{
    // Do some stuff
}
