Creating a cron job that will run a php script

Hi :)

I know how to do the whole time setup * * * * * thing, and cronjobs are already enabled on my server. (I already have some that backup my DBs automatically every night).

But!  Let's say I wanted to run /home/user/public/script.php in a cronjob. Assuming I wanted the time to be * * * * * ... what would my exact command line be? I'd like to NOT use a .sh file if possible, as I'm not familiar with those. Thanks :)
