需要说明的是：
$sql = MySQL::Select('bluepoint_admin','*','','id','1',$set[2],$set[0]);是本人写的一个生成SQL语句的方法，请使用时换成相应该的SQL语句。例如：$sql = "select * from bluepoint_admin order by id desc limit $set[2],$set[0]";

$p -> RsNum('bluepoint_admin',''); 是用于计算result的数量。使用时应在相对应该的 RsNum方法中修改
$result = MySQL::Select($Table_Name,$Fields,$Condition,'id','0','0','0'); 为自己的SQL语句
