title: How do I detect when a user has been idle for a certain time and destroy their session in PHP?
body: <p>I would like to have my PHP website destroy a users session if they have been idle for 5 minutes.  If this does happen, I'd like to present the user with a message stating why they were logged out and redirect them to the login page.</p>
  
  <p>What is the best way to handle this?</p>
  
  <p>I am running on php and myadmin.</p>
  
  <p>Thanks</p>
