改进型
//改进abstract class CommsManager{    const APPT = 1;    const TTD = 2;    const CONTACT = 3;    abstract function getHeaderText();    abstract function make($flag_info);    abstract function getFooter();}class BlogsCommsManager extends CommsManager{    function getHeaderText(){        return 'Blog header';    }    function make($flag_info){        switch($flag_info){            case self::APPT :                return new BloggsApptEncoder();            case self::TTD:                return new BloggsTtdEncoder();            case self::CONTACT:                return new BloggsContactEncoder();        }    }    function getFooter(){        return 'Blogs Footer';    }}
