hi,
i found that the $this pointer does not always point to the current class, as it is supposted to.

run the following example code:
-----
class ca
{
	function debug()
	{
		echo("ca::debug -> ");
		print_r($this);
		echo("<br>");
	}
}

class cb
{
	function debug()
	{
		echo("cb::debug -> ");
		print_r($this);
		echo("<br>");
	}
	
	function test()
	{
		cb::debug();
		ca::debug();
	}
}

$b = new cb;
$b->test();
-----

output is:
cb::debug -> cb Object ( ) 
ca::debug -> cb Object ( ) 

but should'nt it be:
cb::debug -> cb Object ( ) 
ca::debug -> ca Object ( ) 

it seems that when a class is called like class::methode from within another class, the this pointer points to the calling class, not the current running class!!
