Hi,

here is a tricky thing using the parent:: keyword:
There seems to be no way to call a parent function out of a 
parent function!

<?php

class test {

	function test1(){
		echo "parent:test1<br>";
		}
		
	function test2(){
		echo "parent:test2<br>";
		$this->test1();
		}
	
	
	}
	
class sub extends test {

	function test1(){
		echo "sub:test1<br>";
		}
		
	function test2(){
		echo "sub:test2<br>";
		parent::test2();
		}
		
	}
	
	
$a = new sub();
$a->test2();
?>

returns:

sub:test2
parent:test2
sub:test1

Greetings,


Alex
