查询timestamp类型数据
1 $where=" roleid = 8 and lizhi = 0 and branchid IN (".implode(",",$ids).") and regtime between '".$a."' and '".$b."' "; 2 3 $tenderlist=M('admin'); 4 5 $list = $tenderlist->where($where)->select();
regtime 数据类型，timestamp ，例如：‘2017-2-15 9:31:32’.
不可以用时间戳对比查询，不起作用。
between "2017-3-1" and "2017-3-15" 查询 timestamp 时间段的数据。
