Method 'set' can only handle string-typed value

[Timandes]

After i tried this:

<?php
$zk = new Zookeeper("localhost:2181");
$zk->set('/test', array(1));

i got a PHP warning:

PHP Warning:  Zookeeper::set() expects parameter 2 to be string, array given in /home/xxx/zk.php on line 4
PHP Stack trace:
PHP   1. {main}() /home/xxx/zk.php:0
PHP   2. Zookeeper->set() /home/xxx/zk.php:4

Is there any plan to support various types just like Memcached::set?
