在PHP上使用Redis 给多个键值进行自增，示例如下：

$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

$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 “..”

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网页设计。
