As far as I can see in the Help File, Array_Diff was introduced in 4.0.1 and should be in the version you are using. Does it not work? -----Original Message----- From: André Le Tissier [mailto:andre@xxxxxxxxxxxxxxxxx] Sent: 26 June 2005 10:20 To: php-general@xxxxxxxxxxxxx Subject: array_diff php version Help! Array_diff is the perfect function for what I am try to do but I have a php version 4.1.5. Is there any replacement I can use to achieve the same result Many thanks, André Le Tissier ************************ This message has been delivered to the Internet by the Revenue Internet e-mail service ************************* -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
