[PHP] loop inside a loop

[Alan Willsher]

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
