Introduction
In order to have a working Xdebug, you need to ensure two things:
- PHP Xdebug must be configured and enabled in PHP itself
- Your IDE/editor must be configured and requires a way talk to PHP
Configuring PHP Xdebug will slightly differ when configuring it for a dockerized environment. This is due to the fact that Docker versions on different host os have varying implementations of how they connect back to the host.
Most IDE or editors will also require different configurations for how they talk to PHP Xdebug. This is at least most likely the case for xdebug.idekey.
Configure PHP container for Xdebug

The following gives you a step-by-step guide on how to setup PHP Xdebug for the Devilbox depending on what host operating system you are using.
Be reminded that PHP configuration is always done per version, i.e. having it configured for PHP 7.2, does not enable it for any other versions.

Configure your IDE/editor for Xdebug
After you have setup PHP Xdebug as referenced above, you can continue to configure your currently used IDE/editor.
Most IDE/editors will usually be configured in a very similar way, which comes down to two main settings;
Path mapping
The path mapping is a mapping between the file path on your host operating system and the one inside the PHP Docker container.
The path on your host operating system is the one you have set in env_httpd_datadir. In case you have set a relative path in .env, ensure to retrieve the absolute path of it when setting up your IDE config.
The path inside the PHP Docker container is always /shared/httpd.
Important
Even though your path in .env for env_httpd_datadir might be relative (e.g. ./data/www), you need to get the actualy absolute path of it, when setting up your IDE.
IDE key
This is the value you have set in xdebug.ini for xdebug.idekey. In the example of this tutorial, the value was set to PHPSTORM.
