My initial test was done using PHP 5.3.3



The lack of IDN support is still present in 5.3.3



All of Mathias' additional test cases, but the last one are however
handled correctly. I.e. this one is approved:

It should fail. That's probably an edge case, though. The lack of IDN
support is the worst problem.

mathias, you are not testing the current code.  Try it with 5.3.3.

I was trying to post a comment here, but it wouldn’t let me (“ERROR:
Please do not 

SPAM our bug system”), probably because of all the “URLs” I was
trying to post.



Oh well, here’s the comment I tried to post:

Description:
------------
If an URL uses IDN it should be considered valid.



The test script outputs three blank lines. It should output the URL's.



Examples from http://mathiasbynens.be/demo/url-regex



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

echo filter_var('http://✪df.ws/123', FILTER_VALIDATE_URL);

echo "\n";

echo filter_var('http://⌘.ws/', FILTER_VALIDATE_URL);

echo "\n";

echo filter_var('http://➡.ws/䨹', FILTER_VALIDATE_URL);

echo "\n";





Expected result:
----------------
http://✪df.ws/123

http://⌘.ws/

http://⌘.ws/http://➡.ws/䨹





Actual result:
--------------
\n
