Ignoring the extra $ and moving on... I would code it like this... function think(&$i) {

} 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!
$i = $i == 'think' ? 'am' : 'am not'; Cheers, Rob.

Again this is deviating from the spec. A more accurate version would be... $i = $i == 'think' ? 'am' : $i; The spec doesn't say what $i becomes if it's not think. -Stut -- http://stut.net/
