⁠WordPress images with Xdebug3 support for development purposes only.

https://github.com/AndreaDiPietro-ADP/wordpress-docker-compose-xdebug3⁠

This images ENTRYPOINTs writes XDEBUG_CONFIG env variable values

inside a configuration file (/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini) at container startup,

before calling the original Apache ENTRYPOINT script docker-entrypoint.sh apache2-foreground.

So, you can pass all the settings as you write them on the configuration file, remember to not drop xdebug prefix of settings name.

environment:
      XDEBUG_CONFIG: |
        xdebug.mode=debug,develop
        xdebug.client_host=host.docker.internal
        xdebug.client_port=9003
        xdebug.idekey="phpdebugkey"

host.docker.internal should work both on Windows and MacOS DockerDesktop, anyway it can be replaced with the internal IP address used by your host machine.

⁠IDE Settings

IDE setting is quite easy and straight-forward, for example in NetBeans 12.3 put port 9003 and idekey phpdebugkey as stated inside the docker-compose.yml

If it still not works create a PHP file inside the container web directory with

xdebug_info();

to check if Xdebug configuration is set properly... If that does not works, check whether a firewall is active and if it is silently dropping or refusing connection to the 9003 port or if the port is not free for Xdebug.
