范例

示例 #1 ZookeeperConfig::add() example

Add members.


<?php
$client = new Zookeeper();
$client->connect('localhost:2181');
$client->addAuth('digest', 'timandes:timandes');
$zkConfig = $client->getConfig();
$zkConfig->set("server.1=localhost:2888:3888:participant;0.0.0.0:2181");
$zkConfig->add("server.2=localhost:2889:3889:participant;0.0.0.0:2182");
$r = $zkConfig->get();
if ($r)
  echo $r;
else
  echo 'ERR';
?>

以上例程会输出：

server.1=localhost:2888:3888:participant;0.0.0.0:2181
server.2=localhost:2889:3889:participant;0.0.0.0:2182
version=0xca01e881a2
