I wish to run a cron job on one of my accounts but reading through other forums there appear to be many ways to enter the URL. The most common being:
either
/usr/bin/php /usr/home/myusername/public_html/cron.php
or
wget -q -O /dev/null
http://mydomain.com/cron.php
What is the difference? Is either better, or makes more efficient use of resources and will both or either work on dream-hosting?
