Description:
------------
parse_url convert \r\n symbols to _ _.

More:

OK: 
$string = "ftp://login:pass@domain";
array
  'scheme' => string 'ftp' (length=3)
  'host' => string 'domain' (length=6)
  'user' => string 'login' (length=5)
  'pass' => string 'pass' (length=4)

BUG:
$string ="ftp://login:pass@domain\r\n";
array
  'scheme' => string 'ftp' (length=3)
  'host' => string 'domain__' (length=8) /* wtf? */
  'user' => string 'login' (length=5)
  'pass' => string 'pass' (length=4)

------------
if i get strings from file i should use trim before use parse_url.
i think it is bug and parse_url should use trim

 - OR - 

ignore \r\n at the end of line.

Reproduce code:
---------------
$string = "ftp://login:pass@domain";
var_dump(parse_url($string));

$string = "ftp://login:pass@domain\r\n";
var_dump(parse_url($string));

Expected result:
----------------
array
  'scheme' => string 'ftp' (length=3)
  'host' => string 'domain' (length=6)
  'user' => string 'login' (length=5)
  'pass' => string 'pass' (length=4)

Actual result:
--------------
array
  'scheme' => string 'ftp' (length=3)
  'host' => string 'domain__' (length=8) /* wtf? */
  'user' => string 'login' (length=5)
  'pass' => string 'pass' (length=4)
