Yes. I thought it was clear that I understand this. I guess not. My point is that foreach is doing something that isn't immediately obvious. The same is true of your for loop, but to a lesser extent, IMO (as I don't expect your for loop to ONLY read from $i). I don't want to start a discussion on references. I'm just trying to clear up a non-obvious case. S -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
