In the user notes for srand(), richard@zend.com said:

>*ALWAYS* use (double)microtime()*1000000 as your seed.

...
>Anything else is sub-standard.

If so, why not make the seed argument optional, and make the default
(double)microtime()*1000000 when the argument is absent? Save me a
few keystrokes, anyway, and help make sure people don't do it in a 
"sub-standard" fashion...  :)

the seed is optional and php generates a 'good' one.
