Description:
------------
XML_RPC 1.4.7

I try to access a method within a class by XML_RPC as shown on the example from the documentation but I get a response "Unknown method" from the server

Test script:
---------------
Server Side :
<?php
require_once 'XML/RPC/Server.php';

class some_class_name {
function returnTimes2($params) {
$param = $params->getParam(0);

// This error checking syntax was added in Release 1.3.0
if (!XML_RPC_Value::isValue($param)) {
return $param;
}

$val = new XML_RPC_Value($param->scalarval() * 3, 'int');
return new XML_RPC_Response($val);
}
}

$some_object = new some_class_name;

// Here are examples of the various ways to declare "functions":
$server = new XML_RPC_Server(

array('class_times2' =>array('function' => array('some_class_name' => 'returnTimes2'),),),
array('class_times3' =>array('function' => 'some_class_name::returnTimes2'),)

);
?>

Client Side :
<?php
require_once 'XML/RPC.php';

$input = 8;

$params = array(new XML_RPC_Value($input, 'int'));

//$msg = new XML_RPC_Message('class_times2', $params);
$msg = new XML_RPC_Message('class_times3', $params);

$cli = new XML_RPC_Client('/webServices/testServer.php', 'localhost');

$cli->setDebug(1);

$resp = $cli->send($msg);

if (!$resp) {
echo 'Communication error: ' . $cli->errstr;
exit;
}

if (!$resp->faultCode()) {
$val = $resp->value();
echo $input . ' times 2 is ' . $val->scalarval();
} else {
/*
* Display problems that have been gracefully cought and
* reported by the xmlrpc.php script.
*/
echo 'Fault Code: ' . $resp->faultCode() . "\n";
echo 'Fault Reason: ' . $resp->faultString() . "\n";
}
?>

Expected result:
----------------

Sorry : wrong package ...

[2006-04-12 17:17 UTC] stephane at cyberlogic dot ca

Add Package Version

ok, I got it ... Sorry

The doc fooled me :
to declare several functions when you create a new instance of XML_RPC_Server, the first argument is an array of array and not ... several arrays !

By the way, I think there is another error on the server side example : in the class some_class_name, the function returnTimes2 doesnot have the word "function" ...

Sorry for the noise
