Attaching many classes to an XML-RPC server instance can utilize a
lot of resources; each class must introspect using the Reflection
API (via Zend_Server_Reflection), which in
turn generates a list of all possible method signatures to provide to the server class.
To reduce this performance hit somewhat, Zend_XmlRpc_Server_Cache
can be used to cache the server definition between requests. When
combined with __autoload(), this can greatly increase
performance.
An sample usage follows:
<?php
function __autoload($class)
{
Zend_Loader::loadClass($class);
}
$cacheFile = dirname(__FILE__) . '/xmlrpc.cache';
$server = new Zend_XmlRpc_Server();
if (!Zend_XmlRpc_Server_Cache::get($cacheFile, $server)) {
require_once 'My/Services/Glue.php';
require_once 'My/Services/Paste.php';
require_once 'My/Services/Tape.php';
$server->setClass('My_Services_Glue', 'glue'); // glue. namespace
$server->setClass('My_Services_Paste', 'paste'); // paste. namespace
$server->setClass('My_Services_Tape', 'tape'); // tape. namespace
Zend_XmlRpc_Server_Cache::save($cacheFile, $server);
}
echo $server->handle();
The above example attempts to retrieve a server definition from xmlrpc.cache in the same directory as the script. If unsuccessful, it loads the service classes it needs, attaches them to the server instance, and then attempts to create a new cache file with the server definition.
