PHP FILTER_VALIDATE_URL failed to validate

Question

trying to validate the url ( https://www.demo ) using the php, its pass the condition so strange.

I have added the code:

 $url = 'https://www.dsdsis';

 if (filter_var($url, FILTER_VALIDATE_URL)) {
        echo($url ."is a valid URL");
    } else {
        echo($url ."is not a valid URL");
 }

its has to be invalid right?

Answer 1

It meets the criteria for the format of a valid URL. The filter does not actually test to see if the URL actually exists.

If you try your test without the protocol included, http , you will see that it fails. Add the protocol and any combination will be considered valid.
