Extend Cyrilles XmlRpc example with a XmlRpc-callback server, there are many such implementations, see http://www.xmlrpc.com/directory/1568/implementations 2. Access our xmlBlaster C library from PHP. Like this you have tunneled callbacks, high performance, zlib compression See http://www.xmlblaster.org/xmlBlaster/doc/requirements/client.c.socket.html and see how our C# example is doing this: http://www.xmlblaster.org/xmlBlaster/doc/requirements/client.csharp.html 3. You can use Cyrilles XmlRpc PHP code and use blocking get() calls (with timeouts): You would subscribe with PHP but the clients callback queue has set dispatcherActive=false so the messages are collected on server side. Now you can use synchronous get() calls which block until messages are available (see xmlBlaster/src/java/org/xmlBlaster/client/XmlBlasterAccess.java:receive() as a code sample to use for PHP). This approach is very simple but you need to use a dedicated thread in PHP for the blocking get() call (see also http://www.xmlblaster.org/xmlBlaster/doc/requirements/engine.qos.queryspec.Qu eueQuery.html) regards Marcel -------------------------------------------------------
