签到的一些基本逻辑

//签到
    public function userQian(Request $request){
        if(empty($request[‘user_id‘])){
            return [‘code‘=>1,‘msg‘=>‘参数不能为空‘,‘result‘=>null];
        }

        $current_time = date(‘Y-m-d‘,time());
        //调用方法查看今天是否签到过
        $count = Qian::getCount($request[‘user_id‘],$current_time);
        if($count>0){
            return [‘code‘=>1,‘msg‘=>‘已经签过了‘,‘result‘=>null];
        }

        //查询上次签到的时间
        $res = Qian::lastDay($request[‘user_id‘]);

        //当前时间-最近一次签到的时间 = 中间的时间差
        $timec = (strtotime($current_time)-strtotime($res[‘q_time‘]))/60/60/24;

        if($timec==1){
            //表示是连续签到
            $last_days = $res[‘q_day‘]+1;
        }else{
            $last_days = 1;
        }

        //调用方法完成签到的功能
        if(Qian::qiandao($request[‘user_id‘],$current_time,$last_days)){
            return [‘code‘=>0,‘msg‘=>‘签到成功‘,‘result‘=>$last_days];
        }else{
            return [‘code‘=>1,‘msg‘=>‘签到失败‘,‘result‘=>null];
        }

    }
