Bug description:FILTER_VALIDATE_EMAIL invalid punycode regexp
Description:
------------
IDN domains can contain hyphens in its name.
When we convert these domain names to punycode we end up with several
hyphens in
a row.
For example: xn----7sbbtkohtqhvkc8j.xn--p1ai
(кÑлÑÑÑÑа-пенза.ÑÑ)
Yet it is a valid domain name.
The regexp in the ext/filter/logical_filters.c:525 doens't allow multiple
hyphens but two:
> ... (?:(?:(?:xn--)?[a-z0-9]+( ....
So if I try filter_var("[email protected]",
FILTER_VALIDATE_EMAIL) it returns false.
I think valid regexp will be like (?:xn-(-)+)?[a-z0-9]+ yet I can't be sure
since this regexp is
really scary.
Test script:
---------------
<?php
var_dump(filter_var("[email protected]",
FILTER_VALIDATE_EMAIL));
Expected result:
----------------
string(35) "[email protected]"
Actual result:
--------------
bool(false)
