title: Use crontab in Ubuntu with LAMPP
body: <p>I googled for quite some time already, but I still can't find how to setup crontab with lampp.</p>
  
  <p>I need to run a PHP script for every 15 minutes.</p>
  
  <p>So, in bash:</p>
  
  <pre><code>$ sudo -i
  # crontab -e
  </code></pre>
  
  <p>I get a nano editor... what should I type inside?</p>
  
  <p>I tried <code>* * * * */opt/lampp/path/to/script</code> but it's not working.</p>
  
  <p>Can anyone help me?</p>
