Zookeeper::connect

(PECL zookeeper >= 0.2.0)

Zookeeper::connect — Create a handle used to communicate with zookeeper

説明

public function Zookeeper::connect(string $host, callable $watcher_cb = null, int $recv_timeout = 10000): void

This method creates a new handle and a zookeeper session that corresponds to that handle. Session establishment is asynchronous, meaning that the session should not be considered established until (and unless) an event of state ZOO_CONNECTED_STATE is received.

パラメータ

host: Comma separated host:port pairs, each corresponding to a zk server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002"
watcher_cb: The global watcher callback function. When notifications are triggered this function will be invoked.
recv_timeout: The timeout for this session, only valid if the connection is currently connected (ie. last watcher state is ZOO_CONNECTED_STATE).
