PHP Redis 有序列表按参加时间或分值达到时间排序

步骤说明

public function addMemberWinNum($memberId, $num = 1)
{
    $expirationTime = $this->getExpirationTime();
    $existsStatus   = $this->redis->exists($this->rankKey);

    $res = $this->redis->zIncrBy($this->rankKey, $num, $memberId);
    !$existsStatus && $this->redis->expire($this->key, $expirationTime - time());
    return $res;
}

改

/**
 * Redis 有序列表排序按字母排序，现分数修改如下
 * 分数：整数为分数，小数：最大时间-当前时间
 * @param $score
 * @return string
 */
public function encodeScore($score)
{
    $currentTime = time();
    $diffTime    = Constants::MAX_TIME - $currentTime;
    return (double)"{$score}.{$diffTime}";
}

/**
 * 增加用户获胜场次 用于排名
 * @param int $memberId 用户
 * @param int $winNum 胜利次数
 * @return float|string
 */
public function addMemberWinNum(int $memberId, int $winNum = 1)
{
    $expirationTime = $this->getExpirationTime();
    $existsStatus   = $this->redis->exists($this->rankKey);

    // 按游戏分值达到时间排序
    $oldScore = $this->redis->zScore($this->rankKey, $memberId);
    if ($oldScore) {
        $this->redis->zAdd($this->rankKey, bcadd($winNum, $oldScore, 10), $memberId);
    } else {
        $this->redis->zAdd($this->rankKey, $this->redis->encodeScore($winNum), $memberId);
    }

    // 按游戏参加时间排序
    // if ($existsStatus && $this->redis->zExists($this->rankKey, $memberId)) {
    //     $this->redis->zIncrBy($this->rankKey, $winNum, $memberId);
    // } else {
    //     $this->redis->zAdd($this->rankKey, $this->redis->encodeScore($winNum), $memberId);
    // }

    !$existsStatus && $this->redis->expire($this->rankKey, $expirationTime - time());
    return true;
}
