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
