Examples -- Usage examples for the XML_RPC package
Using a Client to Get Info About the Latest PEAR Release
Example 67-1.
<?php
require_once 'XML/RPC.php';
/*
* Get info about the most recently released PEAR package
*/
$params = array(new XML_RPC_Value(1, 'int'));
$msg = new XML_RPC_Message('release.getRecent', $params);
$cli = new XML_RPC_Client('/xmlrpc.php', 'pear.php.net');
// If you want to turn debugging on...
// $cli->setDebug(1);
// If your payload requires extra lines to stay in tact...
// NOTE: The $remove_extra_lines property was added in Version 1.4.6.
// $cli->remove_extra_lines = false;
// If inspect the XML request sent to the server...
// $msg->createPayload();
// logit($msg->payload); // Hypothetical function.
$resp = $cli->send($msg);
if (!$resp) {
echo 'Communication error: ' . $cli->errstr;
exit;
}
if (!$resp->faultCode()) {
$val = $resp->value();
$data = XML_RPC_decode($val);
echo $data[0]['name'] . ' is at version ' . $data[0]['version'];
} 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";
}
// To inspect the XML response from the server...
// NOTE: The $response_payload property was added in Version 1.4.6.
// logit($msg->response_payload); // Hypothetical function.

A Complete Client and Server Combination
Example 67-2.
Here is the server script. It's named xmlrpc.php and located
in the document root of the web server at localhost:
<?php
require_once 'XML/RPC/Server.php';
/*
* Declare the functions, etc.
*/
function returnTimes2($params) {
$obj = new some_class_name;
return $obj->returnTimes2($params);
}
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() * 2, 'int');
return new XML_RPC_Response($val);
}
}
$some_object = new some_class_name;
/*
* Establish the dispatch map and XML_RPC server instance.
*/
$server = new XML_RPC_Server(
array(
'function_times2' => array(
'function' => 'returnTimes2'
),
'class_paamayim_nekudotayim_times2' => array(
'function' => 'some_class_name::returnTimes2'
),
'class_times2' => array(
'function' => array('some_class_name', 'returnTimes2')
),
'object_times2' => array(
'function' => array($some_object, 'returnTimes2')
),
),
1 // serviceNow
);
?>
|
And here is the client script:
<?php
require_once 'XML/RPC.php';
$input = 8;
$params = array(new XML_RPC_Value($input, 'int'));
$msg = new XML_RPC_Message('function_times2', $params);
$cli = new XML_RPC_Client('/xmlrpc.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";
}
?>

Automatically encoding data
The XML_RPC_encode() function automatically converts
PHP data into the format needed by the XML_RPC library.
Example 67-3.
<?php
require_once 'XML/RPC.php';
$data = fetch_row_from_db(); // Hypothetical example.
$params = array(XML_RPC_encode($data));
$msg = new XML_RPC_Message('some_function_name', $params);
$cli = new XML_RPC_Client('/xmlrpc.php', 'pear.php.net');
$resp = $cli->send($msg);
// Process the same way as the other examples...
?>
