Example #1 Zookeeper::getAcl() example

Get ACL of a node.

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

    string(6) "anyone"
  }
