title: PHP redirection/popup: Keep existing page and pop up a new tab
body: <p>I read that we can use the following in the meta tags for redirection to another page after desired number of minutes:</p>
  
  <pre><code>&lt;meta http-equiv="Refresh" content="10; url=http://www.example.com/" /&gt;
  </code></pre>
  
  <p>That is fine if it's acceptable to navigate away from the page that user is on. But what I am trying to do is that instead of navigating to another page, I want to pop up a new browser tab/window and also have the existing page as it is. I would like to do this strictly <strong>without Javascript</strong>.</p>
  
  <p>So consider an example. Say user arrives on 1.php page. Now user will have 10 minutes to read the information on this page. At the end of 10 minutes, I want to pop up a new tab/window which points to the page 2.php and shows the information contained in it. So after the 10 minute, I will have 1.php page as it is and a new tab/window that shows 2.php page. I don't want to disturb the user for whatever he is doing on 1.php and hence want to just pop-up 2.php page.</p>
  
  <p>How can I achieve this <strong>without</strong> using javascript/ajax?</p>
  
  <p>Thank you in advance.</p>
  
  <p><strong>EDIT1:</strong></p>
  
  <p>If there is no way to do achieve this in PHP, how can I achieve this via Javascript? I would want to launch a popup/popunder to 2.php to be able to achieve this functionality and keep the user on the same page as he was on.</p>
  
  <p>Thanks.</p>
