You can use set -e and a simple while loop in bash:

#!/bin/sh

set -e

php_script=$1.php
shift

while true; do
    php $php_script $@
done

Once the PHP script returns an exit code of non-zero the bash script will stop. If you need to run any code after the loop is done, you can do this instead:

while php $php_script $@; do
    continue
done
