• php

• 5.6 (5.6/Dockerfile)
• 7.0 (7.0/Dockerfile)
• 7.1 (7.1/Dockerfile)

See the php image documentation.

But use milk/php-xdebug instead of php.

It should work out of the box with your IDE.

You must specify the following option:

• xdebug.remote_autostart
• xdebug.remote_host

For example, you can run:

php -d xdebug.remote_autostart=1 -d xdebug.remote_host=192.168.99.1 test.php

This image is officially supported on Docker version 1.8.1.

Support for older versions (down to 1.6) is provided on a best-effort basis.

Please see the Docker installation documentation for details on how to upgrade your Docker daemon.
