PHP getting full server name including port number and protocol

Question

In PHP, is there a reliable and good way of getting these things:

Protocol: i.e. http or https Servername: e.g. localhost Portnumber: e.g. 8080

Answer 1

Have a look at the documentation.

You want $_SERVER['SERVER_PORT'] I think.

Answer 2

Here's what I use:

    function my_server_url()
    {
        $server_name = $_SERVER['SERVER_NAME'];

        if (!in_array($_SERVER['SERVER_PORT'], [80, 443])) {
            $port = ":$_SERVER[SERVER_PORT]";
        } else {
            $port = '';
        }

        if (!empty($_SERVER['HTTPS']) && (strtolower($_SERVER['HTTPS']) == 'on' || $_SERVER['HTTPS'] == '1')) {
            $scheme = 'https';
        } else {
            $scheme = 'http';
        }
        return $scheme.'://'.$server_name.$port;
    }

Answer 3

 if(strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,4))=='http') {
        $strOut = sprintf('http://%s:%d', 
                       $_SERVER['SERVER_ADDR'],
                       $_SERVER['SERVER_PORT']);
    } else {
         $strOut = sprintf('https://%s:%d', 
                       $_SERVER['SERVER_ADDR'],
                       $_SERVER['SERVER_PORT']);
    }

 return $strOut;

Try something like that if you want
