Re: Question about array_search

Say I'm trying to add a value to an array, only if it's not already in there somewhere; so I do an array_search to see. The problem is that if the item is at index 0 in the array, array_search gives the same answer as if it's not in there at all.

No it doesn't. If the value is not there, it returns FALSE. If it's at index zero, then it returns zero. if($a === FALSE) { echo 'a is false'; } elseif($a === 0) { echo 'a is zero'; } Read here for an explanation of the above: http://us2.php.net/manual/en/language.operators.comparison.php -- ---John Holmes...
