if you want to check for a method "inside" of a class use:
method_exists($this, 'function_name')
i was a bit confused 'cause i thought i'm only able to check for a method when i got an
object like $object_name = new class_name() with:
method_exists($object_name, 'method_name')
small example for those who didn't understood what i mean ( maybe caused by bad english :) ):
<?php
class a {
function a() {
if(method_exists($this, 'test'))
echo 'a::test() exists!';
else
echo 'a::test() doesn\'t exists';
}
function test() {
return true;
}
}
$b = new a();
?>
the output will be: a::test() exists!
maybe this will help someone
