How do I call a Class->Method from strings?

Question

It it possible to call a class and method from strings?

Something like:

// $_REQUEST['var'] = 'House-Kitchen';

$var = explode('-',$_REQUEST['var']);

echo $var[0]->$var[1];

Answer 1

Yes. its possible. If $var[0] is the name of class then following will work.

call_user_func(array($var[0], $var[1]));

If $var[0] is the name of class instance then following will work.

call_user_func(array(get_class(${$var[0]}), $var[1]));

Answer 2

The better way is to try.

I did try :

$House = new stdClass();
$House->Kitchen = "visible result";

$_REQUEST['var'] = 'House-Kitchen';

$var = explode('-',$_REQUEST['var']);

echo $$var[0]->$var[1];

It works. Be careful : you need to use double $ for the first element (to use variable with $var[0] name).

And be very careful : it's a high security breach (you allow everyone to call methods on current defined class).
