Re[2]: [PHP] Simple: Whats wrong with this?
Hello Jake, Wednesday, March 17, 2004, 5:00:52 PM, you wrote: $correct++; JM Does this always work? In my timesheet app, I have to do $counter = $counter JM + 1, because for some reason the $counter++; doesn't work. It just doesn't JM work, no incrementation of the variable. Is there something in php.ini that JM can prohibit this from working? ++ is a _post_ increment. This means it'll returns $correct first and then increment it by one.

Yes, that's a pre-increment operator. Quite different to a post-increment. You need to use the right one depending if your variable exists already, etc. -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
