Description:
------------
Hey,
if you validate a given url with the function filter_var and the param FILTER_VALIDATE_URL with the flag FILTER_FLAG_PATH_REQUIRED you also get true back if there is no path.

The function is happy with the result if there is a simple / at the end of the function. But thats not a valid path. A valid path would be at least 1 char after the /. I added you some examples below.

thanks and greetings
Leo

Test script:
---------------
php -r 'var_dump(filter_var("http://php.net/", FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED));' // <- will be okay, but it's not.

php -r 'var_dump(filter_var("http://php.net/foobar", FILTER_VALIDATE_URL, FILTER_FLAG_PATH_REQUIRED));' // <- that would be okay.

Expected result:
----------------
filter_var() should return false if the path is not given/empty because according to the documentation if forces the requirement of a path.

Actual result:
--------------
filter_var is okay with an url if there is a / at the end.

Well, in a strict sense you're right, but I don't think we can
change that for BC reasons.  The documentation should clarify that
FILTER_FLAG_PATH_REQUIRED also accepts URLs with an empty path
(path-empty in RFC 3986 parlance).
