php script run by cron job

Hi there, I already managed it to run a php script by cron, but now I cant remember the exact syntax. Somehow it does not work. /var/log/messages tells me that cron has called the line, but it never runs. I did try to run the line without cron and it works. Here is the how I did it:

14 8 * * *      root  /usr/local/bin/php /home/www/cron/statistics.php

Does anybody see an error in this? Thanx, Merlin PS: I also tried to run this as www but same results
