I'm trying to setup a function from user code inside a defined object or a
class definition but it doesnt seem to work. Am i doing it right? Is there
something i need to know... is it even possible?
I know create_function can be used to create a function and it returns the
ident to run the function later on, lookup create_function on php.net and it
seems possible. Now i wonder if you can actually assign this function inside
a class. My final goal is to create a set of functions or objects that will
be able to "implement" interfaces to object classes, which is something
missing to the PHP language.

<?php
class cls_a {
function a(){
echo 'allo';
}
}
class impl_a {
function get_impl_b(){
return array('', 'echo "Hello world";');
}
}
$a = new cls_a();
$b_code = impl_a::get_impl_b();
$a->b = create_function($b_code[0], $b_code[1]);
$a->a();
$a->b();
?>
