Not for windows, but...

I've got a couple of long-running PHP scripts, that have a shell script wrapping it. You can optionally return a value from the script that will be checked in the shell-script to exit, restart immediately, or sleep for a few seconds -and then restart.

Here's a simple one that just keeps running the PHP script till it's manually stopped.

#!/bin/bash
clear
date
php -f cli-SCRIPT.php
echo "wait a little while ..."; sleep 10
exec $0

The "exec $0" restarts the script, without creating a sub-process that will have to unravel later (and take up resources in the meantime). This bash script wraps a mail-sender, so it's not a problem if it exits and pauses for a moment.
