在PHP上使用Redis 给多个键值进行自增，示例如下：

? 1 2 3 4 5 $set['money'] = $this->redis->hIncrByFloat($key, $hour .'_money', $data['money']); $set['ip'] = $this->redis->hIncrBy($key, $hour .'_ip', $data['ip']); $set['uv'] = $this->redis->hIncrBy($key, $hour .'_uv', $data['uv']); $set['pv'] = $this->redis->hIncrBy($key, $hour .'_pv', $data['pv']); $this->redis->hSet($key, $hour, array($data['money'], $data['ip'], $data['uv'], $data['pv']));

如果这样写可能需要请求五次，可以通过 Eval 方法来一次完成，大大提高效率

? 1 2 3 4 5 6 7 8 9 $script = 'local money = redis.call("hIncrByFloat", KEYS[1], ARGV[1], ARGV[2]);'; $script .= 'local ip = redis.call("hIncrBy", KEYS[1], ARGV[3], ARGV[4]);'; $script .= 'local uv = redis.call("hIncrBy", KEYS[1], ARGV[5], ARGV[6]);'; $script .= 'local pv = redis.call("hIncrBy", KEYS[1], ARGV[7], ARGV[8]);'; $script .= 'local val = money ..",".. ip ..",".. uv ..",".. pv;'; $script .= 'redis.call("hSet", KEYS[1], ARGV[2], val);'; $script .= 'return val;'; $result = $this->redis->evaluate($script, [$key, $hour, $hour .'_money', $data['money'], $hour .'_ip', $data['ip'], $hour .'_uv', $data['uv'], $hour .'_pv', $data['pv']], 2); var_dump($result);

Redis 用的 Lua 语法，我也不熟悉，这个字符串拼接方式也很特别的是两个点号 “..”

? 1 2 3 money ..",".. ip ..",".. uv ..",".. pv 拼接后 0.01,1,2,3

以上这篇Redis使用Eval多个键值自增的操作实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
