Thi is an example intial repo for debuging PHP with Xdebug inside Docker. Using VS Code.
The Nginx, Dockerfile, docker-compose.yml and xbebug.ini are a start point for developing php web applications locally.
You should modified these files to your need and I do not advice using these sample files into production.
To run everything you must run the following command (positioned in the same folder as yout docker-compose.yml file):
docker-compose -p <desired-name> up -d.
Install the felixfbecker.php-debug extension.
You can create a debug configuration by going to Debug > Add Configuration... > PHP, but configuration file is included in .vscode/launch.json with the correct folder maping.
Add a breakpoint, and click on "Listen for XDebug" in the top left hand corner. Load your page, and you should get debugging information:
