In PHP 7.4, the difference set of the calculated array is checked with an index to compare whether the request parameters in the body are equal to the arrays in the cache

RTC 邀请接受通话：/mobile/rtcs/invite-accept ( mobile/rtc/invite-accept )

1、请求参数列表
( 1 ) user_name：必填，用户名称
( 2 ) call_mode：必填，通话方式，voice_call：语音通话；video_call：视频通话

2、输入数据验证规则
( 1 ) 必填：user_name、call_mode
( 2 ) 字符串：user_name、call_mode
( 3 ) 范围([voice_call, video_call])：call_mode
( 4 ) 判断房间是否存在，是：响应失败

3、操作数据
( 1 ) 设置RTC 邀请接受通话数据的缓存键
( 2 ) 从缓存中取回RTC 邀请接受通话数据
A、如果不存在，则序列化，将RTC 邀请接受通话数据存放到缓存供下次使用，在缓存中永久保留
B、如果存在，则反序列化，带索引检查计算数组的差集，如果差集不为空，将RTC 邀请接受通话数据存放到缓存供下次使用，在缓存中永久保留

        // 设置RTC 邀请接受通话数据的缓存键
        $redisCache = Yii::$app->redisCache;
        $gisRtcInviteAcceptCacheKey = implode(':', ['gis', 'rtc', 'invite', 'accept', $identity->group_id]);

        // 从缓存中取回RTC 邀请接受通话数据
        $gisRtcInviteAcceptCacheData = $redisCache[$gisRtcInviteAcceptCacheKey];

        $requestGisRtcInviteAccept = [
            'user_name' => $user_name,
            'call_mode' => $call_mode,
        ];

        if ($gisRtcInviteAcceptCacheData === false) {
            // 将RTC 邀请接受通话数据存放到缓存供下次使用，在缓存中永久保留
            $redisCache->set($gisRtcInviteAcceptCacheKey, serialize($requestGisRtcInviteAccept));
        } else {
            $gisRtcInviteAccept = unserialize($gisRtcInviteAcceptCacheData);

            // 带索引检查计算数组的差集
            $result = array_diff_assoc($gisRtcInviteAccept, $requestGisRtcInviteAccept);

            if (!empty($result)) {
                // 将RTC 邀请接受通话数据存放到缓存供下次使用，在缓存中永久保留
                $redisCache->set($gisRtcInviteAcceptCacheKey, serialize($requestGisRtcInviteAccept));
            }
        }
