Question

Here is what I would do in JavaScript. Is there any way to do it in php?
I am working on a project that needs this functionality but cannot use JavaScript.

setInterval ( "checkHistory()", 1000 );

function checkHistory() {
   if (oldHistLength != history.length) {
      removegateway();
      oldHistLength = history.length;
   }
}

Sorry to say that it’s not possible to do that using PHP. Your only option is to use JavaScript somewhere.

You can however achieve what I believe you’re trying to do with another technique – PHP Sessions and Request URIs.

This involves storing the user’s accessed URLs into a variable (or you could use MySQL) which can be referenced anywhere on the website within that current session.

Here’s an (untested) example:

<?php
session_start();

// Retrieve/create the current list
if( isset($_SESSION['history']) ) {
    $history = $_SESSION['history'];
} else {
    $history = new array();
}

// Add the current URL to the history array
array_push($history, $_SERVER['REQUEST_URI']);

// Do anything else you want to here

// Store the array again
$_SESSION['history'] = $history;
?>
