PHP - Do Command After Certain Amount Of Time?

[superwormy]

Basically what I want to do is ONLY perform a command after a certain period of time has passed.

So for instance, run a big long complicated RegExp UNTIL a certain number of seconds pass, then do something else.

Is there a way to do this in PHP?

maybe this will help?
