or: 3. refactor the functionality in PHP so that trim or others *can* be used in extensions. I would not pick option 2, especially not if you're going to call this function a lot. Calling a PHP function directly involves a lot more overhead than just calling a C-function. cheers, Derick -- http://derickrethans.nl | http://xdebug.org Like Xdebug?
