Yes, but it works differently. If the user typed in the URL of your page
(instead of clicking a link) then you can't go back from PHP, so you need to
be careful. Here's some sample code:


<?php
    $referer = getenv("HTTP_REFERER");

    if ($referer)
    {
        $url = $referer;
    }
    else
    {
        // can't go back... try JS instead
        $url = "javascript:history.back()";
    }

    echo "<a href=\"$url\">Back Button</a>";
?>



Cheers
