Without completely disabling Xdebug from the php.ini I'm currently unable to stop Xdebug from running for all cli commands. Previously I would toggle remote_autostart to enable if I needed to debug through cli. My problem is in particular causing issues with composer, effectively making it unrunnable. Composer claim that composer should restart without Xdebug running if they see it is running, this is supposedly fixed from composer version 1.3 forward, but I'm using composer 1.7.3.

This is running inside my alpine PHP-FPM docker container but that shouldn't really make a difference. This issue has previously been experienced by a co-worker inside vagrant too so I can get his environment details too if needed.

php.ini Xdebug settings which I set myself:

zend_extension=/var/www/html/xdebug/modules/xdebug.so

xdebug.remote_enable=1

xdebug.remote_port=9000

xdebug.show_local_vars=0

xdebug.var_display_max_data=10000

xdebug.var_display_max_depth=20

xdebug.show_exception_trace=0

#xdebug.remote_autostart=1

xdebug.remote_host=172.20.0.1

xdebug.idekey="PHPSTORM"

xdebug.remote_log=/srv/www/var/log/xdebug.log

php -i | grep 'xdebug' output:

Xdebug log when making cli connection:

Undocumented Behavior

XDEBUG_CONFIG environment variable has the undesired effect of causing Xdebug to run on every execution as described at the bottom of this article. https://www.larrykagan.com/xdebug-on-docker/

For me the solution was just to stop using export XDEBUG_CONFIG="ide=PHPSTORM" as that setting is already in my ini anyway.
