You're good at those... but I'll pull off the top of my head that the array overhead ought to require more memory due to the need for indexes (maybe) but at least for internal tree structure. The speed ought to slow down since the array will need to be created and built. Then using in_array() I'm guessing is a linear search since values aren't sorted (at least I can't image the values being sorted). You could probably overcome the speed issue using an array with the values as indexes instead of the values and using isset() to check for membership of the value :) Cheers, Rob. -- .------------------------------------------------------------. | InterJinn Application Framework - http://www.interjinn.com | :------------------------------------------------------------: | An application and templating framework for PHP.
