    This question actually belongs on the PHP General mailing list.

    As for echoing into a variable, the only way that's really
possible is with output buffering (ob_start(), ob_get_contents(),
ob_end_clean(), et al).  However, you don't need (and shouldn't want)
to do this here.  Instead, as your snippet really won't do much of
anything useful, you should (entirely) rewrite your code to look
something like this, for an HTML table:

        echo $_SERVER['PHP_SELF'].'?'.PHP_EOL;
        echo '<table>'.PHP_EOL;
        foreach ($_GET as $key => $value) {
            echo ' <tr>'.PHP_EOL;
            echo '  <td>'.$key.'</td>'.PHP_EOL;
            echo '  <td>'.$value.'</td>'.PHP_EOL;
            echo ' </tr>'.PHP_EOL;
        echo '</table>';

    However, since it looks almost as if you're trying to build a
query string based upon the supplied GET variables, you may want to
try looking into http_build_query().
