The main cost in that is that array_filter has to create a copy of the array. An alternative is using an FilterIterator or generator or such which would make this a pipeline step. (with iterators there are multiple function calls, while the function descriptor is cached, making them relatively cheap) I'd focus on improving those. johannes -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
