title: PHP or JavaScript or jQuery cookie expire 5 minutes
body: <p>How would I use PHP to set a cookie to expire in 5 minutes?
  I'm familar with <code>setcookie()</code>, but not with it's time property. An explanation would be nice.</p>
  
  <p>Can somebody please point me to the right direction (or include a sample code)?</p>
  
  <p>Thanks a lot. :)</p>
  
  <p>(P.S. I woudn't mind a solution in jQuery or in JavaScript either.)</p>
