At the end of each script run all variables are discarded and the memory becomes eligible for garbage collection. So it doesn't make a difference whether you keep posting back to PHP_SELF or you follow a twisty path from one script to the next. Of course, at any given point, you may still be using a lot of memory if you are being inefficient or you need to handle an awful lot of data. You can unset arrays you no longer need, and you can just generally look at how you're storing data to determine that it provides the best balance of resource usage. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
