From manual page: http://www.php.net/filter.filters.validate

platform: PHP 5.4.4 (Debian Wheezy)

There is a documentation problem with the FILTER_VALIDATE_URL. In english and in french (i can't verify in other langages)

In french :

"Attention, une URL valide ne doit pas spécifier le protocole HTTP http://, aussi, des validations ultérieures seront requises pour déterminer si l'URL utilise un protocole attendu"

In english :

"Beware a valid URL may not specify the HTTP protocol http:// so further validation may be required to determine the URL uses an expected protocol, e.g. ssh:// or mailto:."


"may not" = "ne pourrait pas"

But the doc (in french AND english) is not right and tell a wrong expected result.
Url MUST use protocol.


See Doc Bug #40675 but this part bug is not corrected.






Test script:
---------------
var_dump(filter_var('example.com', FILTER_VALIDATE_URL);
// return false

var_dump(filter_var('http://example.com', FILTER_VALIDATE_URL);
// return the url

Expected result:
----------------
Change the documentation
