You can use like this:

<?php
    //open socket
    if(!($fp = fsockopen("localhost", 80)))
    {
        print("Couldn't open socket!<br>\n");
        exit;
    }
    //make request for document
    fputs($fp, "HEAD /test/phpsecurity/protecthttp.php HTTP/1.0\r\n");

    //send username and password
    fputs($fp, "Authorization: Basic " .
        base64_encode("mia:secret") .
        "\r\n");

    //end request
    fputs($fp, "\r\n");

    //dump response from server
    fpassthru($fp);
?>

Try to change username and password at line 13, like:

base64_encode("youyou:secret")
