$PHP_SELF not set !

We've got a problem : http://php.hellekin.com/test/php_self.php http://php.hellekin.com/test/php_self.phps for the source doesn't seem to work. Gotta check if it comes from Apache or PHP or my client. So, here is the code : <?php

$reg    = ini_get('register_globals') ? "on" : "off";

echo <<<EOD <table align="center"

                border="0"
                width="600"
                cellspacing="1"
                cellpadding="4"
                bgcolor="#000000">

        <tr     bgcolor="#cccccc">

                <th     align="left"> register_globals </th>
                <td     bgcolor="#ccccff"> $reg </td>

        </tr>

        <tr     bgcolor="#cccccc">

                <th     align="left"> PHP_SELF </th>
                <td     bgcolor="#ccccff"> $PHP_SELF </td>

        </tr>

        <tr     bgcolor="#cccccc">

                <th     align="left"> _SERVER['PHP_SELF'] </th>
                <td     bgcolor="#ccccff"> $_SERVER[PHP_SELF] </td>

        </tr>

        <tr     bgcolor="#cccccc">

                <th     align="left"> REQUEST_URI </th>
                <td     bgcolor="#ccccff"> $REQUEST_URI </td>

        </tr>

</table> EOD; echo '<p>The last line of this file is : print_r($PHP_SELF);</p>'; print_r($PHP_SELF); ?>
