Description:
------------
If you manually extract the query string from http://example.com?foo=bar&\x00foo=bar2&foo=bar3 and then use parse_str() on the result it is different than if you use parse_url() and then parse_str(). This is loosely related to https://bugs.php.net/bug.php?id=66976.

Test script:
---------------
$url = "http://example.com?foo=bar&\x00foo=bar2&foo=bar3";
list($path, $query_string) = explode('?', $url, 2);
// Use parse_url() and then parse_str()
$parts = parse_url($url);
parse_str($parts['query'], $parsed_qs);
var_dump($parsed_qs);
// Ouptput: array(2) {
//  ["foo"]=>
//  string(4) "bar3"
//  ["_foo"]=>
//  string(4) "bar2"
//}

// Use parse_str()
parse_str($query_string, $parsed_qs);
var_dump($parsed_qs);
// Output: array(1) {
//  ["foo"]=>
//  string(3) "bar"
// }

Expected result:
----------------
I expect the second result to be the same as the first.
