说明

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

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 connections is currently connected (ie. last watcher state is ZOO_CONNECTED_STATE).
