Description:
------------
Actually  get_headers parse the wrong hostname.


Test script:
---------------
<?php

print_r(get_headers('http://www.youtube.com@www.google.com.hk'));

Expected result:
----------------
Return the youtube response headers.

Actual result:
--------------
Return the google response headers.

Since Google can not be accessed, the actual results are as follows:

Warning: get_headers(http://...@www.google.com.hk): failed to open stream: Network is unreachable in /home/hjy/Desktop/test2.php on line 3

In the given URI, www.youtube.com is the user(info)[1], and
www.google.com.hk is the domain.  I fail to see why this
interpretation would be a bug.
