note 8911 added to srand

*ALWAYS* use (double)microtime()*1000000 as your seed. Do *NOT* just use time(). Do not add an extra 0 to make it "bigger". Take care to call srand() only *ONCE* per script. Calling (double)microtime()*1000000 once, and only once, per script gives you the maximum "randomness" you can get. Anything else is sub-standard. If you want to understand why, there's a lot of reading you need to do... I don't know enough to point you to the best text to get started on this reading. For now, just trust the PHP Developers, okay? http://www.php.net/manual/function.srand.php
