title: First time setting up a cron job
body: <p>I'm totally new to cron jobs.</p>
  
  <ol>
  <li>How do I set up a cron job that runs a PHP function once per day, at midnight?</li>
  <li>What filetype does the cron job file need?</li>
  </ol>
  
  <p>I have only FTP access to my website so I'm not the administrator on the server. I have Googled and read related questions here on Stack Overflow, without any results.</p>
