class and create function

[Anon]

basically, i have written a self extending class system. i achieved this by using something like:

[class_number] extends [parent] { ..... etc
and then replacing [class_number] and [parent] with the correct number, whatever. this means that we can still keep the main function in the class, ie class_number{ asd... }

this is so that i can run through all the main functions and effectivly construct a modular system. (doing "[parent]::parent;")

the looming mountain i cant seem to climb over is running a function within class based on a url variable. ie, if the url is a.php?run=do_me, the function in the class called do_me should be called. im trying to achieve along the lines of something like:
$func = create_function('','\$this->$run();');
echo $func();

i cant seem to get anywhere on this.. if someone can give a hand..

omg! it was as easy as ..... well, i dunno what.

all i had to do was use $this->$run();

i had no idea that you could use a var when calling functions belonging to a class.
