First some sample code:


class foo {
	var $bar = 0;
	function increase () {
		$this->bar++;
	}
}

$foo = new foo;

print "Bar: " . $foo->bar . "\n";
call_user_method('increase', $foo);
print "Bar: " . $foo->bar . "\n";

$foo->increase();
print "Bar: " . $foo->bar . "\n";


This will output:

Bar: 0
Bar: 0
Bar: 1

It appears that call_user_method is working on a copy of the object rather than the object itself.
