Subject: PCS (PHP Code Service)
From: francois@php.net (=?UTF-8?Q?Fran=c3=a7ois_Laupretre?=)

Hi,

I'd like to open a discussion about a new PHP extension named PCS.

PCS stands for 'PHP Code Service' and it is (yet) another way to mix C 
and PHP code in extensions.

Some months ago (January 2015), we had come to the conclusion that two 
issues needed to be solved : allow the PHP code to be opcache-d, and 
avoid loading every script at RINIT. PCS proposes a solution for both 
via a stream wrapper and an autoloader.

During this discussion, it also became clear that two different sources 
of PHP scripts should be supported : some want to embed and distribute 
scripts in the compiled module, and others want to store them in a 
separate location on the host. So, PCS supports both architectures or 
even a mix of both.

The documentation is available at http://pcs.tekwire.net :

- the 'Introduction' document details the pros and cons of the different 
approaches,
- and a tutorial describes in details how to embed the MongoDB PHP 
library in the MongoDB C extension.

If this discussion results in a positive consensus, and because PCS may 
potentially be used to rewrite parts of core extensions from C to PHP, 
I'll write an RFC proposing to include it in the 7.1 core distrib.

Note : don't use the 'pecl install' command to get PCS, download from 
PECL. I still need to find a workaround for the 'pecl' command bug.

Regards

François
