PHP how to get the base domain/url?

Question

function url(){
    if(isset($_SERVER[\'HTTPS\'])){
        $protocol = ($_SERVER[\'HTTPS\'] && $_SERVER[\'HTTPS\'] != \"off\") ? \"https\" : \"http\";
    }         


        

Answer 1

This works fine if you want the http protocol also since it could be http or https. $domainURL = $_SERVER['REQUEST_SCHEME']."://".$_SERVER['SERVER_NAME'];
