xdebug.ini for xdebug 3 / php 8.1

[herberlin]

Images using xdebug 3 must use the new configuration parameters as said in the xdebug configuration; for me the following file worked fine:

xdebug.ini

zend_extension=xdebug
[xdebug]
xdebug.mode=develop,debug
xdebug.client_host=host.docker.internal
xdebug.start_with_request=yes

When working with docker compose you'll need a so called extra_host - mapping for the internal gateway. Working for me:

docker-compose.yml

  php:
    container_name: apache_php
    # image: mobtitude/php-xdebug:8.1-apache
    build: docker/apache2/build
    ports:
      - 8080:80
      - 9001:9003
    volumes:
      [...]
    extra_hosts:
      - host.docker.internal:host-gateway

In the docker/apache2/build I placed your Dockerfile and the xdebug.ini as shown above.

Thank you very much for sharing and
cheers
