Bug description:filter_var returns false on valid URLs

Description:
------------
Hello,

I am currently testing script attached which is supposed to validate URLs

The URL as you can see is a valid URL but the 4 var_dump's done return
false. Here is a test run result:

string(29) "http://my-domain.mydomain.com"
bool(false)
bool(false)
bool(false)
bool(false)

I tested my_domain.mydomain.com and it returned the domain correctly. while
on the '-' dash sign it returns false


Test script:
---------------
<?php
        $URL = "http://my-domain.mydomain.com";
        var_dump($URL);
        var_dump(filter_var($URL, FILTER_VALIDATE_URL));
        var_dump(filter_var($URL, FILTER_VALIDATE_URL,
FILTER_FLAG_SCHEME_REQUIRED));
        var_dump(filter_var($URL, FILTER_VALIDATE_URL,
FILTER_FLAG_HOST_REQUIRED));
        var_dump(filter_var($URL, FILTER_VALIDATE_URL,
FILTER_FLAG_SCHEME_REQUIRED | FILTER_FLAG_HOST_REQUIRED));
?>

Expected result:
----------------
return the URL in case it is valid even if it contains '-'

Actual result:
--------------
returns false
