说明

public Zookeeper::__construct ([ string $host = [, callable $watcher_cb = null [, int $recv_timeout = 10000 ]]] )

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.

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).


错误/异常

This method emits PHP error/warning when parameters count or types are wrong or could not init instance.

Caution Since version 0.3.0, this method emits ZookeeperException and it's derivatives.
