redis和memcache列出所有key
//redis $redis = new Redis(); $redis->connect("host", "port"); $redis->select(0); //redis默认有0-15 16个数据库 此处选择0 $redis->dbsize(); //返回有多少个key $keys = $redis->keys("*"); //使用通配符列出所有key var_dump($keys); //memcache $servers = array(array("host1", "port1"), array("host2", "port2")); $mem = new Memcache(); $mem->addServer("host1", "port1"); $mem->addServer("host2", "port2"); $all_items = $memcache->getExtendedStats(‘items‘); $options = array("host1:port1","host2:port2");
foreach($servers as $server){ $option = $server[0] . ":" . $server[1]; if(isset($all_items[$option][‘items‘])) { $items = $all_items[$option][‘items‘]; foreach ($items as $number => $item) { $str = $memcache->getExtendedStats(‘cachedump‘, $number, 0); $line = $str[$option]; if(is_array($line) && count($line) > 0){ foreach ($line as $key=>$value) { $keys[] = $key; } } } } } var_dump($keys);
