PHP 5.3.2 (cli)

FILTER_VAR returns false on valid URL's such "".
Without minus-sign it will return the string as positive result.

In Bug-Search I found the hint, that it already would be fixed in 5.2.13.
It seems, that in 5.3.2 this bug was born again 

Test script:
$url = "";
var_dump(filter_var($url, FILTER_VALIDATE_URL));

Expected result:
string ""

Actual result:
bool (false)
