Having a state flag around rand() and srand() which indicates, upon a call
to rand, whether or not srand() has been called is a great idea. When PHP is
acting as part of a web page, seeding the random number generator is a
fairly tricky thing to maintain.
If you don't do it in the module, a user would have to do it in the PHP
environment, and that is a little more difficult.
