Start Xdebug session for Symfony CLI commands

My dev setup includes PHP 8 and Xdebug 3 in a docker container for a Symfony project.

Currently I use xdebug.start_with_request=yes, but I don't like the performance impact that has.

How do I start an Xdebug session on demand for Symfony console commands?

Solution

  • Set Xdebug mode to off(xdebug.mode = off; in your settings), set the environment variable XDEBUG_MODE = debug only for the script you are executing:

    XDEBUG_MODE = debug bin/console run:my:command

    Now Xdebug will only be enabled while you execute bin/console run:my:command.

    You mention that you are executing your scripts inside a docker container, but that shouldn't change things too much. You could pass the environment variable in the docker exec call with the --env argument.
