title: How to add visited pages urls into a session array?
body: <p>Everytime the user visit a page, the page url will be stored into an array session. I want to have 10 elements in the array only. So that 10 elements will save 10 latest visited page urls. Here is my codes :</p>
  
  <pre><code>&lt;?php
  $currentpageurl = $_GET['username'];
  
  $urlarray=array();
  
  $urlarray[] = $currentpageurl;
  
  $_SESSION['pageurl']=$urlarray;
  
  foreach($_SESSION['pageurl'] as $key=&gt;$value)
      {
      echo 'The value of $_SESSION['."'".$key."'".'] is '."'".$value."'".' &lt;br /&gt;';
      }
  ?&gt;
  </code></pre>
  
  <p>I tested the code, it always overwrite the element in the array with new visited page, thus it has only 1 element in the array. How to make it not to overwrite the element?</p>
