 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; }
