Local nicknames or * unqualified names MUST NOT be used.
Rejection of so-called partial domains because of "missing" dot is not following section 2.3.5 of RFC 5321.
To validate expected input I have to add a "protocol" as a prefix, and return true or false, and further validate the input.$r = filter_var(''this.doesnt.it.required://'.$host, FILTER_VALIDATE_URL);return ($r !
Description: An exception occurred while processing your request.
It says FQDNs are permitted, and com, org, or va are (well, may be) valids FQDNs. Some TDLs (although few of them) have MX RRs, the for example "[email protected]" is correct.
FILTER_VALIDATE_EMAIL is discarding valid e-mail addresses containing IDN.
Returns: PHP Version: 5.2.14 //On MY server, may be different depending on which version you have installed.Often I see some code like the following:$value = "12";if( filter_var($value, FILTER_VALIDATE_INT) )The above works as intended, except when $value is "0". For the correct behavior, you have not only to check if it is equal (==) to false, but also identic (===) to FALSE:$value = " 0 ";if( filter_var($value, FILTER_VALIDATE_INT) === FALSE )I hope, I could help.Contrary to what documentation implies, the FILTER_NULL_ON_FAILURE seem to affect any validation filter, not just FILTER_VALIDATE_BOOLEAN.When the flag is used on a validation filter other than FILTER_VALIDATE_BOOLEAN, as expected the filter will return NULL instead of FALSE upon failure.This is quite useful when filtering a POST form with filter_input_array(), where you don't want to check what field is invalid and what field is missing.
I've been using that since PHP 5.2, and as of PHP 5.6.8 it still works.
