How to Force Page Refresh on Back Button Click in Single PHP File Routing?

How to Refresh Page on Back Button Click for Single PHP File Routing

In your code snippet, you're using .htaccess to redirect all traffic to a single index.php file and dynamically include different HTML pages based on the parameters GET parameter. However, you're having issues with the back button not refreshing the page.

To address this, consider implementing one of the following solutions:

Option 1:

Create a new PHP file that displays a timestamp or unique number that updates every time the page is refreshed. This file can be included at the bottom of the index.php file to force a page refresh when the back button is pressed.

<code class="php">// newpage.php
header("Cache-Control: no-store, must-revalidate, max-age=0");
header("Pragma: no-cache");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
echo time();
?></code>

<code class="html"><!-- index.php -->
<!-- ...your existing code... -->
<?php include "newpage.php"; ?></code>

Option 2:

Use JavaScript to store the data from dynamically created elements in a hidden input field with display: none. When the page loads (onload event), check the value of the hidden field. If it's "no," set it to "yes" and continue. If it's "yes," reload the page.

<code class="html"><input type="hidden" id="refreshed" value="no">
<script type="text/javascript">
  onload = function () {
    var e = document.getElementById("refreshed");
    if (e.value == "no") e.value = "yes";
    else {
      e.value = "no";
      location.reload();
    }
  };
</script></code>

These solutions should refresh your page when the back button is pressed, enabling the desired functionality without requiring complex .htaccess configurations or other browser-specific methods.
