The long winded way to write this would > be: If you *KNOW* you set the default value: $this = $something ? $that : $this; Crude, but effective, Captain -- Spock If you're not *SURE* $this has a value: $this = ($something ? $that : (isset($this) ? $this : NULL)); Some of those parens might be un-needed, but I'd get confused without them, never mind PHP being confused or not :-) Course, I gotta say that maybe you're coming at this wrong in the first place, if you have to change $this based on $something to $that but $this already has a value... Maybe you should have figured out what $this should be back when you first initialized it? Maybe not. Can't tell without seeing more code. -- Like Music? http://l-i-e.com/artists.htm
