Answer 1

$username="root";
$password="root";
$database="test";

    function Save($name)
    {
        global $username;
        global $password;
        global $database;

        $link = mysql_connect('localhost', $username, $password);
        if (!$link) {
            die('Could not connect: ' . mysql_error());
        }
        @mysql_select_db($database) or die( "Unable to select database");
        $query = "INSERT INTO test (name)" .
                 "VALUES ('" . $name . "')";
        mysql_query($query);
        mysql_close();
    }
