Sorting array takes at least O(n*log n) (well, with comparison sort, but that's what you'd have to use I assume), while linear search can be done in O(n). So no profit here. If you *know* the array is sorted, binary search function could be useful, but I'm not sure how wide the use case for it would be. > lines of "function binary_search(string target, array arrayToSearch, bool > sort)". Doing this, the function can preform a sort if required to, thus > not needing to sort a array that is already sorted. Array function's name would have to start with array_ prefix. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
