            global $dbh;

            return $dbh->Edit($sql,$params);

        }



    }

实体层：

class proM extends BaseModel

{

    private $proName;

    private $proDetail;

    private $proPic;

    private $proPic1;

    private $proAttr;

    private $proTaxis;

    private $proIsHome;

    private $proIsTJ;

    private $proIsCTJ;

    private $proIsDel;

    private $proAddTime;

    private $proisHot;

    private $proisPorClass;

    private $proisYN;

    private $proGL;

    private $proSeoT;

    private $proSeoK;

    private $proSeoD;

    private $proBH;

    private $FK_proClass;

    private $proModel;

    private $proPrice;

    private $proDiscount;

    private $proHit;

    private $proURL;

    private $proisKdWords;

    private $proisKdDone;

    private $proFL;

}

使用：

$m=new proM();

$m->proName='代码';

$m->proDetail='php开发';

$m->Update('proID=:proID',array(proID=>1));
