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硕编程。
