is there a way for a function to exec by itself

[o0katz0o]

I'm making a game sort of thing in PHP and I was wondering if there was a way in PHP that I can pause the execution of a function after x seconds. I don't want the whole script to stop working though, so for example
// function 1

(pauses for 10 seconds) {
// function 2
}

// function 3

i want the script to execute like normal, but pause for 10 seconds before executing function 2, so it would execute function 1 and function 3 then 10 seconds later, execute function 2

this is exactly like the fork() statement found in MOO programming
