The cron job:
* * * * * /usr/bin/wget http://infiniteresponder.mrcomptech.com/sendmails.php
I thought wget was just an ftp program and thought that after wget downloaded the file then it needs a command processor, in this case since wget is downloading a php script the command processor would be /usr/bin/php.
I don't understand why this works, but it would seem that wget must be more than just an FTP program and has support for php.
In the meantime I had create this cron job, which does work or course but it is being run as root.
* * * * * /usr/bin/php /var/www/infiniteresponder.mrcomptech.com/web/sendmails.php > /dev/null
I prefer putting the cron job in the 'Sites' tab since it's a convenient place to put all cron jobs.
Thanks again Till!
