Description:
------------
Attached patch fixes the issue.

Test script:
---------------
$url = 'http://www.example.com#fra/gment';
echo $url . "\n";
var_dump(parse_url($url));

$url = 'http://www.example.com?p=1/param';
echo $url . "\n";
var_dump(parse_url($url));

// No host, should return false
$url = 'http://#fra/gment';
echo $url . "\n";
var_dump(parse_url($url));

// No host, should return false
$url = 'http://?p=1/param';
echo $url . "\n";
var_dump(parse_url($url));

Expected result:
----------------
http://www.example.com#fra/gment
array(3) {
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(15) "www.example.com"
  ["fragment"]=>
  string(9) "fra/gment"
}
http://www.example.com?p=1/param
array(3) {
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(15) "www.example.com"
  ["query"]=>
  string(9) "p=1/param"
}
http://#fra/gment
bool(false)
http://?p=1/param
bool(false)

Actual result:
--------------
http://www.example.com#fra/gment
array(3) {
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(19) "www.example.com#fra"
  ["path"]=>
  string(6) "/gment"
}
http://www.example.com?p=1/param

  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(19) "www.example.com?p=1"
  ["path"]=>
  string(6) "/param"
}
http://#fra/gment
array(3) {
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(4) "#fra"
  ["path"]=>
  string(6) "/gment"
}
http://?p=1/param
array(3) {
  ["scheme"]=>
  string(4) "http"
  ["host"]=>
  string(4) "?p=1"
  ["path"]=>
  string(6) "/param"
}
