> Subject: [PECL-DEV] Proposal for a new extension AMFEXT
>
>
> Hello everybody,
>
> I would like to propose to add a new PECL extension for
> encoding and decoding ActionScript Messages (AMF) for faster
> data exchange between PHP and Flash.
> The extension has already been implemented, tested and
> integrated by the amfphp project, and the people SabreAMF are
> doing the same. If the extension is present amfphp takes
> advantage of it otherwise it uses the PHP serializer.
> The idea of this extension is to provide the core elements
> of the AMF encoding and decoding while demanding the higher
> level handling to PHP. The extension has just two functions
> amf_encode and amf_decode, while flexibility has been
> provided by some callback functions that control how objects
> are encoded and decoded. Moreover recordsets can be encoded
> quite efficiently with a specific callback.
>
> There is an implementation detail that I would like to point
> out. During encoding I was initially using the smart_str type
> for storing the encoding, but it was scaling bad with big
> data to encode. I've solved the problem with a StringBuilder
> data structure that is able to scalable well with data, and
> also it stores references to PHP string if they are longer
> than a threshold, something that happens frequently during
> encoding. Internally the data structure is made of a list of
> allocation blocks, and each allocation block is a sequence of
> raw datas or references to zval. I don't know if this
> StringBuilder could be useful for other uses, in the
> meanwhile I've packed it as a resource, that can be used
> independently on AMF encoding.
> In particular the StringBuilder can be sent to a stream
> without flattening into a string.
>
> The extension has been currently published on
> http://www.teslacore.it/wiki/index.php?title=AMFEXT where it
> is possible to obtain details on the encoding and the
> StringBuilder. I am planning to move the source code into the
> amfphp project in SourceForge or better in a new project. The
> extension is licensed under PHP License Version 3.
>
> Do you think that such extension could be interesting or useful?
