Re: Recursive Threading with PHP and MySQL.

recursion is something that can be fun and practical at times, other times its a bad coder trying to do something they think is clever. use it wisly. <?php function power($num, $power = 1) { if ($num != 2) $power = power(($num/2), $power+1); return $power; } echo power(16); ?> this example is purposely coded bad to show you how recursion can mess up with bad error checking. this example will work. change to power(30) and you'll get a segfault because $num will allways equal anything but 2. this gives you a starting point on recursion. -- Chris Lee lee@mediawaveonline.com "Alawi" <albaity@php4web.com> wrote in message news:002201c17dc2$75276cd0$753f47d4@mcsh2l7jqy8bgj...
