Zookeeper::__construct

Create a handle to used communicate with zookeeper

&reftitle.description; 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.

&reftitle.parameters;

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

&reftitle.errors;

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

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