ZookeeperConfig::add — Add servers to the ensemble
$members
[, int $version = -1
[, array &$stat = NULL
]] ) : voidmembersComma separated list of servers to be added to the ensemble. Each has a configuration line for a server to be added (as would appear in a configuration file), only for maj. quorums.
versionThe expected version of the node. The function will fail if the actual version of the node does not match the expected version. If -1 is used the version check will not take place.
statIf not NULL, will hold the value of stat for the path on return.
This method emits ZookeeperException and it's derivatives when parameters count or types are wrong or fail to save value to node.
Example #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
