Hi can you put a loop inside a loop? what I want to do is have something looping every 1 second and then something else looping once every 10 seconds. something like a combination of these two.. $x = 0; while ($x < 1000) { echo "1"; $x++; sleep(1); } $y = 0; while ($y < 100) { echo "2"; $y++; sleep(10); } but at the same time so it would output something like 1111111111211111111112111111111121111111112 Thanks
