Description:
------------
Basically PHP does not convert the DNS name 'localhost' to '127.0.0.1' like it 
should.

Test script:
---------------
<?php
//THIS WON'T REPRODUCE IF YOU DON'T RUN IT ON VISTA

echo gethostbyname('localhost');

//Basically applies to any other PHP function that resolves 'localhost'
echo mysql_connect('localhost', 'root', '');

?>

Expected result:
----------------
127.0.0.1
[some link identifier]

Actual result:
--------------
localhost
false
