这篇文章主要介绍了使用PHP导出Redis数据到另一个Redis中的方法,需要的朋友可以参考下
从某个 Redis db 导出数据到另一个 Redis db 的PHP脚本： 代码如下:$from = '127.0.0.1:6200/6'; $to = '127.0.0.1:6200/8'; $from_redis = redis_init($from); $to_redis = redis_init($to); $keys = $from_redis->keys('*'); $count = 0; $total = count($keys); foreach($keys as $key){ if(++$count % 100 == 1){ echo "$count/$total\n"; } $type = $from_redis->type($key); switch($type){ case Redis::REDIS_STRING: $val = $from_redis->get($key); $to_redis->set($key, $val); break; case Redis::REDIS_LIST: $list = $from_redis->lRange($key, 0, -1); foreach($list as $val){ $to_redis->rPush($key, $val); } break; case Redis::REDIS_HASH: $hash = $from_redis->hGetAll($key); $to_redis->hMSet($key, $hash); break; case Redis::REDIS_ZSET: $zset = $from_redis->zRange($key, 0, -1, true); foreach($zset as $val=>$score){ $to_redis->zAdd($key, $score, $val); } break; } } function redis_init($conf){ $redis = new Redis(); preg_match('/^([^:]+)(:[0-9]+)?\\/(.+)?/', $conf, $ms); $host = $ms[1]; $port = trim($ms[2], ':'); $db = $ms[3]; $redis->connect($host, $port); $redis->select($db); return $redis; }
