PHP 實現簽到功能

如圖所示：

實現上圖功能，創建兩張表：簽到獎品表、簽到記錄表（這個表可以再拆分出一個表）

 

 

    /**
    *功能：計算兩個時間戳之間相差的日時分秒
    *$begin_time  開始時間戳
    *$end_time    結束時間戳
    */ 
    public function timediff($begin_time,$end_time){
        if($begin_time < $end_time){
            $starttime = $begin_time;
            $endtime = $end_time;
        }else{
            $starttime = $end_time;
            $endtime = $begin_time;
        }

        //計算天數
        $timediff = $endtime-$starttime;
        $days = intval($timediff/86400);
        //計算小時數
        $remain = $timediff%86400;
        $hours  = intval($remain/3600);
        //計算分鍾數
        $remain = $remain%3600;
        $mins = intval($remain/60);
        //計算秒數
        $secs = $remain%60;
        $res  = array("day" => $days,"hour" => $hours,"min" => $mins,"sec" => $secs);
        return $res;
    }
