Subject: Compatibility library for extensions
From: francois@php.net (=?UTF-8?Q?Fran=c3=a7ois_Laupretre?=)

Hi,

Some of you may be interested by a project I just released at 
https://github.com/flaupretre/pecl-compat.

This is a compatibility library. The objective is to minimize the pain 
of making a PHP extension compatible with both PHP 5 and 7, while 
allowing to keep a single code tree.

Of course, it does not bring solutions to every cases you may encounter 
and some 'ifdef' will still remain, but it solves a lot of issues, 
especially related to changes in zend_string and zend_hash, which were 
the most annoying in my case.

For an example of an extension using this compatibility layer, look at 
https://github.com/flaupretre/pecl-pcs.

Feel free to comment, test, and suggest improvements.

Regards

François
