Problem With FWrite Within A Cronjob

I have the following file:


<?php
$ccyymmdd = date("Y - m - d (G,i)");
$file = fopen("dbbackups/".$ccyymmdd.".php","w");
// Write stuff here
fclose($file);
?>


When run from my browser it works fine. When I run from a cron job my Cron Daemon sends me a report:

Warning: fopen(dbbackups/2009 - 10 - 25 (11,10).php): failed to open stream: No such file or directory in /home/xxxxx/public_html/dbbackupcron.php on line 7

My Cron:
/usr/local/bin/php -q /home/xxxxxxx/public_html/dbbackupcron.php

Anyone know a work around for this? Perhaps using CURL instead of PHP?

You may need to use the absolute path to refer that file.

Got it working with CURL in the end, thanks for your help
