phpcredits()
Go ahead right now and run a file with just this function in it. What you’ll see is a list of the developers responsible for the version of PHP running on your machine.
You don’t have to save the princess eight times before getting to the credits, but sadly there’s no PHP theme music to play in the background as they scroll by.
The optional parameter will let you display only sections of the credits.
