Setting up xdebug with swoole could be a bit of a hustle especially if application is containerized and you are running swoole and xdebug in a docker container with IDE on the host.

Here’s what worked for me.

Here I’m using hyperf framework, but I think issues and instructions should be similar for other swoole based frameworks (mezzio, resonance etc). Swoole 5.0.1 + PHP 8.1 natively support xdebug.
