This is as a convenience to programmers. Often arrays have things added or removed as you're coding -- not having to worry about removing a trailing comma for an element that is now the last one, or adding one to previous elements when adding items to the list is a small but useful timesaver. Perl does this as well. I'm not sure which other languages do, but I like it. -- [ joel boonstra | gospelcom.net ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
