OK Stut, for the > $10,000 bonus....what should you return here and what is the least > amount of code you can do it in? I'm not sure here, but are you being sarcastic? ;) Ignoring the extra $ and moving on... I would code it like this... function think(&$i) { $i = 'am'; } If I call think, then I am thinking, therefore $i should become 'am'. If you return 'am' rather than changing $i IMHO you're deviating from the spec. [/snip] No sarcasm at all. And you are spot on!
