schemeThe id of authentication scheme. Natively supported: "digest" password-based authentication
certApplication credentials. The actual value depends on the scheme.
completion_cbThe routine to invoke when the request completes. One of the following result codes may be passed into the completion callback: - ZOK operation completed successfully - ZAUTHFAILED authentication failed
This method emits PHP error/warning when parameters count or types are wrong or operation fails.
Since version 0.3.0, this method emits ZookeeperException and it's derivatives.
