$_SERVER['PHP_AUTH_USER'] is empty
<p>I tried to update the php version of my VPS but it didn't work and my provider didn't help me well, so i downgrade it to the previous version. </p>

<p>I am now working with PHP 5.2.17 (cli). Everything was working properly in this version.</p>

<p>Since this upgrade and downgrade, the variable <code>$_SERVER['PHP_AUTH_USER']</code> is empty. (In the php.ini, <code>register_globals</code> is 'on' and <code>$_SERVER['PHP_SELF']</code> is properly working).</p>

<p>It ask me properly my username and password and i success to connect but i need to use <code>$_SERVER['PHP_AUTH_USER']</code>.</p>

<p>I tried <code>$_SERVER['PHP_AUTH_USER']</code>, <code>$_SERVER['AUTH_USER']</code>,  <code>$_SERVER['REMOTE_USER']</code> nut none is working. (but im never getting any error, just a blank value...)</p>
