How to check for an empty get index?

I wanted to reproduce PHP version easter egg (http://www.0php.com/php_easter_egg.php).

As you can see, the get parameter has no name : ?=PHPE9568F36-D428-11d2-A769-00AA001ACF42

I can check the URL with $_SERVER['REQUEST_URI'], but is there a way to check using only the $_GET array ?

I tried $_GET[''] but it doesn't appear to work.

This seemed interesting so I made a quick solution:

Request ?param1=asd&param3=123&=PHPE9568F36-D428-11d2-A769-00AA001ACF42

PHP

function getFullRequest()
{
    $tmp = explode('&', $_SERVER['QUERY_STRING']);
    $request = [];
    if (!empty($tmp) && is_array($tmp)) {
        foreach($tmp as $item) {
            $req = explode('=', $item);
            if (!empty($req) && is_array($req)) {
                $request[$req[0]] = $req[1];
            }
        }
    }

    return $request;
}

$request = getFullRequest();
var_dump($request);

Result

array (size=3)
  'param1' => string 'asd' (length=3)
  'param3' => string '123' (length=3)
  '' => string 'PHPE9568F36-D428-11d2-A769-00AA001ACF42' (length=39) // <- necessary value

$_GET is empty in this instance so no, it's not possible.

In addition to $_SERVER['REQUEST_URI'] you can use $_SERVER['QUERY_STRING'] though.

[QUERY_STRING] => =PHPE9568F36-D428-11d2-A769-00AA001ACF42
[REQUEST_URI] => /test.php?=PHPE9568F36-D428-11d2-A769-00AA001ACF42
