Bug description:FILTER_VALIDATE_URL does not allow - in domain name
Description:
------------
FILTER_VALIDATE_URL documentatin says that it does filtering according to
rfc2396, but in fact filter_var fails to conform RFC.
Hostname definition in rfc is as follows:
hostport = host [ ":" port ]
host = hostname | IPv4address
hostname = *( domainlabel "." ) toplabel [ "." ]
domainlabel = alphanum | alphanum *( alphanum | "-" ) alphanum
toplabel = alpha | alpha *( alphanum | "-" ) alphanum
so it should allow "-" dash symbol in domainnames (both domain name and TLD
name).
In other hand it SHOULD NOT allow "_" symbol in the domain name, as it is
against specification (right now it allows).
Test script:
---------------
first case also should validate successfully
php -r 'var_dump(filter_var("http://ea-sd.com";, FILTER_VALIDATE_URL));'
bool(false)
php -r 'var_dump(filter_var("http://easd.com";, FILTER_VALIDATE_URL));'
string(15) "http://easd.com";
