一个简单的分页 和分页总数
$p=input('p')?input('p'):1;
$limit=6;
$res=db('points_log')->where(['p_uid'=>$uid,'del_id'=>0])->field('p_log_id,p_uid,integral_source,integral,creat_time')->page($p,$limit)->order('creat_time desc')->select();
$count=db('points_log')->where(['p_uid'=>$uid,'del_id'=>0])->count();
//计算分页总数
$page=ceil($count/$limit);
