Back to previous page

I have a JavaScript on my sites which takes readers back to the page from which they came, thus:
<a href="#" onClick="history.go(-1)">back</a>

Now, many of my readers surf with JavaScript dis-enabled!

Please, does anyone know of a PHP script which goes pack to the previous page?

Cyrogenius replied to someone on the 5th September and gave the following code which works well, thank you. Iain

<?php
$this = basename($_SERVER['PHP_SELF'], '.php');
$prev = intval($this) - 1;
$next = intval($this) + 1;
$prevlink = $prev . '.php';
$nextlink = $next . '.php'; echo "<a href=\"$prevlink\">&lt;&lt; Previous</a> | <a href=\"$nextlink\">Next &gt;&gt;</a>";
?>
