cron job

Hi all, I have a problem with excuting a daily PHP script, I put this script in the cron.daily folder so that its excuted daily, but I noticed that its never excuted, I made sure of the permissions on the cron file, and here is the content of the cron file << #!/bin/sh lynx -dump localhost/daily_jobs.php > /dev/null >> I tried to remove the > /dev/null , but nothing changed and when I excute the file manually by issuing ./daily_jobs.php it works just fine !! so what the problem could be ? Thanks
