php连接zookeeper 报Uncaught exception 'ZookeeperNoNodeException' with message 'no node'

<?php
$zookeeper = new Zookeeper('locahost:2181');
$aclArray = array(
  array(
    'perms'  => Zookeeper::PERM_ALL,
    'scheme' => 'world',
    'id'     => 'anyone',
  )
);
$path = '/path/to/newnode';
$realPath = $zookeeper->create($path, null, $aclArray);
if ($realPath)
  echo $realPath;
else
  echo 'ERR';
?>

在创建/path/to/newnode的时候
报错Uncaught exception 'ZookeeperNoNodeException' with message 'no node'，通过在git上找到了例子

/** 
 * Equivalent of “mkdir -p” on ZooKeeper 
 * 
 * @param string pathThepathtothenode∗@paramstringvalue The value to assign to each new node along the path 
 * 
 * @return bool 
 */ 
 public function makePath(path,value = ”) { 
parts=explode(′/′,path); 
parts=arrayfilter(parts); 
subpath=”;while(count(parts) > 1) { 
subpath.=′/′.arrayshift(parts); 
 if (!this−>zookeeper−>exists(subpath)) { 
this−>makeNode(subpath, $value); 
 } 
 } 
 }“`

原来要创建多层次的node，需要进行递归创建。
