I noticed that erratum the moment after I sent the email. Oh, if only emails could be edited *after* being sent… The output would be: cmp(1, 2); // -1 cmp(1, 1); // 0 cmp(2, 1); // 1 There should’ve been a minus sign on the third one, a typo. But I’d forgotten that comparison functions actually go the other way round. I suppose this proves my point that cmp() would make things easier ;) -- Andrea Faulds http://ajf.me/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
