在PHP上使用Redis 给多个键值进行自增,示例如下:
1
2

$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服务器之家。
