It's not an endless loop, only a very long during loop.
$ntries is counts from 0 .. 3 (at 4 there's a return).
If e.g. $ntries is 3 then you have a call
sleep(30*3*3) = sleep(270) what means that the program
waits 4 and half minutes!
If you change the sleeping time e.g. to sleep($ntries*$ntries)
you'll see that the loop stops.
