One note about speed: I just had an impressing speedup with a very tiny change. Having an array with 1500 Elements, the following code took about 15 seconds: <?php for($intItem = 0; $intItem < count($aItemData); $intItem++) { // ... do something ... } ?> By just assigning the number of items to a variable and comparing against this, reduced the total execution time to 0.9 seconds (yes TO, not BY) <?php $intCount = count($aItemData); for($intItem = 0; $intItem < $intCount; $intItem++) { // ... do still the same ... } ?> ---- Manual Page -- http://www.php.net/manual/en/function.count.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+37318 Delete -- http://master.php.net/manage/user-notes.php?action=delete+37318&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+37318&report=yes Search -- http://master.php.net/manage/user-notes.php
