thinkphp比较两个时间戳之间消耗时间方法

代码如下

    /**
     * 计算两个时间戳之?
     * @param $begin_time
     * @param $end_time
     * @return array
     */
    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;
        }
        $timediff = $endtime - $starttime;
        $days = intval( $timediff / 86400 );
        $remain = $timediff % 86400;
        $hours = intval( $remain / 3600 );
        $remain = $remain % 3600;
        $mins = intval( $remain / 60 );
        $secs = $remain % 60;
        $res = array( "day" => $days, "hour" => $hours, "min" => $mins, "sec" => $secs );
        return $res;
    }
