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

Use parse_url() like this:

function url(){
    if(isset($_SERVER['HTTPS'])){
        $protocol = ($_SERVER['HTTPS'] && $_SERVER['HTTPS'] != "off") ? "https" : "http";
    }
    else{
        $protocol = 'http';
    }
    return $protocol . "://" . parse_url($_SERVER['REQUEST_URI'], PHP_URL_HOST);
}

Here is another shorter option:

function url(){
    $pu = parse_url($_SERVER['REQUEST_URI']);
    return $pu["scheme"] . "://" . $pu["host"];
}
