Do not use array_search() as a boolean test, it returns mixed results, it will cause issues withthe zero index as younoted. Instead use it to match an array key, then see if the key exists with isset() and compare it to the item you mean to add to the array. There lots of other ways too, possibly more overhead, but less code. For example you could just add the item to the array blindly, then run array_unique() on the array. -- Greg Donald Zend Certified Engineer http://gdconsultants.com/ http://destiney.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
