title: How to put access time limit on a php
body: <p>I am trying to put limit on a PHP script. For example in <code>index.php</code> user enters some code/password and is redirected to <code>content.php</code>
  there he can use my script lets say <code>final.php</code>.</p>
  
  <p>I want something like this that after using my script, if he want to use it again. He need to wait for 5 minutes or so.</p>
  
  <p>I.e. user must not be able to get access to <code>final.php</code> (from <code>content.php</code>) and instead he must get an error saying please wait 5 minutes.</p>
  
  <p>I am new to PHP so please help me.</p>
