Somewhere in your code there is something that is assigning to $hello. Find everything that's doing that and look at each instance in detail. > > -Stuart > > -- > Stuart Dallas > 3ft9 Ltd > http://3ft9.com/ > As you've said that your excerpt doesn't replicate the problem, it's not that useful really to accurately illustrate it. I would say for definite that it's some of the surrounding code, probably something similar to this: class Hello { private $_world = 'World'; function __construct(){} function test() { $GLOBALS[strtolower(get_class($this))] = $this; } } $clsHello = new Hello(); $clsHello->test(); echo 'The variable $hello is '.gettype($hello)."\n".print_r($hello,true); There are probably many ways to achieve this, I can't think of a sane reason for any of them though!
