The official composer docker image and simply "copying" theĬomposer executable over to the base php image. Pesky warnings regarding "SSH keys being exposed in a repository". However, we will not use SSH keysĪny longer but simply authenticate via password. We will still rely on an always-running docker setup that we connect to via an SSH ConfigurationĪs I feel it's closer to what we do in CI / production. Setting up PhpStorm with Xdebug for local development on Dockerīut will also cover the "remaining cases" of debugging php-fpm and php worker processes. Debug code executed via php-fpm, cli or from a worker.To get automatic notifications when the next part comes out :) If you want to follow along, please subscribe to the RSS feed The previous part wasĭocker from scratch for PHP 8.1 Applications in 2022 Part-4-2-phpstorm-docker-xdebug-3-php-8-1-in-2022Īll published parts of the Docker PHP Tutorial are collected under a dedicated page atĭocker PHP Tutorial. I hope all these tips will help you improve the speed of your development environment.All code samples are publicly available in myĭocker PHP Tutorial repository on Github. In order to set the remote host to the XDEBUG_CONFIG should be set remote_host=. According to how you run docker, this setting could be a changing IP address or if you're using Docker for Mac. The best example is probably the remote_host. XDebug settings can be overridden using the XDEBUG_CONFIG environment variable, which means there is no need to update the xDebug config file every time you have to change a setting or if you and your teammates need different settings. The only thing required is to change the value of the variable and restart the container. We now have a convenient way to enable xDebug only when needed and save some precious time not waiting in front of loading pages. When the variable is missing, xDebug will stay activated. The container can be started either with docker-compose or docker run and xDebug activated by setting the environment variable DISABLE_XDEBUG to false and disabled by setting it to true. ![]() You can do the same thing if you're running your tests without PhpStorm.Īs an example here is how you can run PhpUnit with xDebug activated:Įnter fullscreen mode Exit fullscreen mode When starting the "on-demand" mode, PhpStorm adds -d zend_extension=xdebug.so to the PHP CLI options, which enables the extension. The -d allows defining an entry in the PHP configuration. PhpStorm is not doing magic for the "on-demand" mode but taking advantage of the -d PHP CLI option. Tips 3: Use the on-demand mode without PhpStorm I'll let you dig in the documentation as it will be better explained than if I do it myself. ![]() It will enable xDebug only when debugging tests, which will allow running your test at full speed most of the time. Tips 2: Use the on-demand PhpStorm mode when debugging testsĪs explained in the PhpStorm documentation, an "on-demand" mode is available. This being said, how can we manage to start xDebug when needed? Another idea is that if you have an xdebug.ini file in the PHP configuration directory, rename it to something else,, for instance. So, disable it by commenting the path to the extension in the. The best way to avoid xDebug slowing everything down is by not having xDebug running. I found a few tips that helped me go back to the same state as before.Īhah… Yes, you can thank me for this one. My tests were running slower than before, and every request took way too much time. Nevertheless, the last time I had to set it up was more straightforward, thanks to PhpStorm, and I don't think the difficulty to set up is a valid excuse anymore.Īnd I had a speed issue. It made me an almost perpetual member of the var_dump debug team. I have to admit that I've always been lazy when it came to set up xDebug as it felt tedious the few times I've to do it.
