Recently Patrick released a new testing version of AMFPHP which supports the Flex2 AMF3 object encoding.

Some changes:

– $this->methodTable is DEAD. All methods in /services are now considered remotely accessible, unless you set them to protected or private (PHP5) or start the method name with an (_)
– Returning a mysql_query will now return either an Array or an ArrayCollection depending on the setting in gateway.php
– browser now brings up the brand spanking new Flex 2-based service browser

This is a testing version since it has still a lot of limitations and it has been tested only on PHP5. I see the post today and I haven’t tested yet…
You can read here for a detailed list of changes

Moreover Patrick plans to add to amfphp the Flex Data Services (read what they are). In this post he got a brief explanation about flash player/FDS communication and ask for developers to help him with the developement of FDS in amfphp (you might need a copy of charles).
