The latter asks "Is this key in the array?" whereas isset() adds "and is its value not null?" While isset() is every-so-slightly faster, this should not be a concern. Use whichever makes sense for the context here. Hi David, Thank you for the explanation. It's nice to know the difference between them. Since they are equivalent for my use, I went with array_key_exists, simply because it makes more sense to me in English. ;) Thanks again to everyone. I got it to work _and_ there are no more errors!!! Angela -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
