There are several ways to combine php-scripts with cron.

Today i realized that using CURL is an option to.

So basicly you could just do the following in commandline / Teminal.app:

curl http://your.server.ip.or.name/your-php-script-file.php

If that works for you, just continue with a manual cron-entry or using cronnix to add the cron-job
