Like mentioned by php at maisqi dot com, this function does not support IDN, and instead for reinventing the wheel we can use the idn_to_ascii function in the intl module. Example: <?php function validateUrl($url) { $idn = idn_to_ascii($url); return filter_var($idn, FILTER_VALIDATE_URL); } ?> How it works, is that idn_to_ascii converts the multi-byte url to a punycode ascii string. Below is the example in these docs <?php echo idn_to_ascii('täst.de'); ?> Returns: xn--tst-qla.de This is the actual url stored in the DNS That string can also be reversed by using idn_to_utf8() ---- Server IP: 69.147.83.197 Probable Submitter: 46.9.207.119 ---- Manual Page -- http://www.php.net/manual/en/function.filter-var.php Edit -- https://master.php.net/note/edit/107450 Del: integrated -- https://master.php.net/note/delete/107450/integrated Del: useless -- https://master.php.net/note/delete/107450/useless Del: bad code -- https://master.php.net/note/delete/107450/bad+code Del: spam -- https://master.php.net/note/delete/107450/spam Del: non-english -- https://master.php.net/note/delete/107450/non-english Del: in docs -- https://master.php.net/note/delete/107450/in+docs Del: other reasons-- https://master.php.net/note/delete/107450 Reject -- https://master.php.net/note/reject/107450 Search -- https://master.php.net/manage/user-notes.php
