Suggestions for getting PHP to act as an AMF client

I have been looking at Zend AMF and AMFPHP to see if either can operate as a client and I am not finding anything that says it definitely can or cannot operate as a client.

Is this possible withe either of these libraries? Are there other solid AMF libraries for PHP that will provide a client interface?开发者_如何学编程

I would suggest using SabreAMF from this site, but this is not a checked way.
