How would you translate the following script into something that would
work with register globals set to 'off'?

---

$envs = array("HTTP_REFERER", "HTTP_USER_AGENT", "REMOTE_ADDR",
"REMOTE_HOST", "QUERY_STRING", "PATH_INFO");

foreach($envs as $env) {
if(isset($$env))
print("$env: ${$env}<br />\n");
}

---

The obvious solution would be to change

if(isset($$env))
to
if(isset($_SERVER[$env]))

however that doesn't work. Any ideas? Thanks.
