title: Running a PHP script completely on server side
body: <p>I'm having a problem where putty gets regularly disconnected. So, when I run a PHP script from the terminal, it always gets interrupted. The script is supposed to run several hours, so I'm not having any luck with it.</p>
  
  <p>How can I completely run this from the server side? I'm reading about cron jobs, but I'm having a hard time understanding at this time. Is there any alternative to cron for what I need?</p>
  
  <p>I have several script PHP files that need to be run, one by one, or perhaps two at a time. Any ideas?</p>
