The problem is that it is a rather unusual thing to do. I don't mean removing an element, that is very common, but you are implying that you know you don't have duplicates and you want a fast way to remove an element by value in that case. To me that means you built your array badly. If the values are unique then they should be the keys, or at least a representation of the value should be the key such that you don't need to scan the entire hash for the element when you need to access it. And removal is just like any other access. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
