<p>I use this function, but it does not work all the time. Can anyone give a hint?</p>

<pre><code>function sofa_get_uri() {
    $host = $_SERVER['SERVER_NAME'];
    $self = $_SERVER["REQUEST_URI"];
    $query = !empty($_SERVER['QUERY_STRING']) ? $_SERVER['QUERY_STRING'] : null;
    $ref = !empty($query) ? "http://$host$self?$query" : "http://$host$self";
    return $ref;
}
</code></pre>

<p>I want to retrieve the link in address bar (exactly) to use it to refer user back when he sign out. The urls are different:</p>

<pre><code>http://domain.com/sample/address/?arg=bla

http://domain.com/?show=bla&amp;act=bla&amp;view=bla

http://domain.com/nice/permalinks/setup
</code></pre>

<p>But I can't get a function that works on all cases and give me the true referrer.</p>

<p>Hint please.</p>
