pecl-memcache Issue #23

This repository reproduces the issue described in websupport-sk/pecl-memcache#23.

In short, on PHP 7.1, when using memcache as the session.save_handler, the following warning occurs when calling session_start():

Warning: session_start(): Failed to read session data: memcache (path: tcp://127.0.0.1:11211)

The same code and settings does not result in this warning on PHP 7.0.

Running the Example

This example uses Docker and Docker Compose to build two images and run two containers (one for PHP 7.0 and one for PHP 7.1). Both are identical, expect for the version of PHP used.

git clone https://github.com/ramsey/pecl-memcache-issue-23
cd pecl-memcache-issue-23/
docker-compose up

Now, the two containers should be running, and you can open the following in your browser to verify:

• http://localhost:8001/info.php (should be running PHP 7.0)
• http://localhost:8002/info.php (should be running PHP 7.1)

To test the session_start() issue and see the warning, open the following:

• PHP 7.0: http://localhost:8001/ (the session should work as expected)
• PHP 7.1: http://localhost:8002/ (session_start() should generate a warning)

See the scripts in docker/ for an understanding of how everything is configured and running.
