Entweder das, oder du wählst explizit aus was du haben willst
PHP:
$arr = get_defined_vars();
$white = Array("SERVER_NAME",
"SERVER_ADMIN");
echo '<table border="1">';
foreach($arr AS $var => $val)
if(in_array($var,$white))
echo '<tr><td>['.$var.']</td><td>'.$val.'</td></tr>' . "\n";
echo '</table>';
