You don't need to declare variables, simply initialize them before using them in a way that wouldn't auto-initialize. For example: $foo = $i++; In this case $foo is auto-initialized, but you are incrementing $i without explicitly initializing it to 0. This code should be: $i = 0; $foo = $i++; It is common sense really. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
