Once upon a time, I put together a working environment with PHP, xDebug, Docker and PhpStorm. Since then, I have been dragging it from project to project and felt happy. For those who find it difficult to set up a local environment with Docker and xDebug, I am posting this config with explanations. Here below we will create a Docker image with xDebug installed, configure PhpStorm and explain a working configuration for Docker Compose.
