Take a look at the $_SERVER superglobal.

<?php
//example
echo $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URL'];

parse_url() can help you, or some of the php string functions, like strtok()

You say that you want the URL of the last page, which can be found in the $_SERVER['HTTP_REFERER'] variable.

Beware that this value is not reliable as it can be freely changed by the client.

If you want a more accurate way of finding the last page, you can use sessions. Here's an example:

session_start();
$last_page = $_SESSION['pageurl'];
$_SESSION['pageurl'] = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URL'];

// $last_page now contains a more reliable value for the last url
