When are infinite loops are useful in PHP?

Question

While reading through the great online PHP tutorials of Paul Hudson he said

Perhaps surprisingly, infinite loops can sometimes be h

Answer 1

I think a point is being missed... there aren't really infinite loops (you would be stuck in them forever), rather while(true){...} and co are useful when you have non trivial exit conditions (e.g. those coming from a third-party library, or a limit which would take a lot of time to calculate but can be worked out incrementally inside of the loop, or something relying on user input).

It shouldn't be surprising that not every loop can be concisely stated as a for, while or do loop without using break.
