Xdebug is a powerful, open source debugging/profiling tool for PHP. It's packaged as a PHP extension and can be incredibly helpful when fine-tuning your PHP application. Xdebug has many configurable options available that are handy for configuring Xdebug to your specific needs or integrating it with an IDE like PHPStorm. Using custom Xdebug configs in a Nanobox environment is simple, but does requires a little setup.
Include Xdebug in Your Project
The PHP Engine lets you specify what Zend extensions to include in your project with the
zend_extensions config in your
boxfile.yml, the file used to define and configure your app's environment. For performance reasons, I recommend including Xdebug only in your local dev environment, which is done using the
dev_zend_extensions > add config in your
run.config: engine: php engine.config: dev_zend_extensions: add: - xdebug
Create a Custom xdebug.ini
To define non-default Xdebug settings, include a custom
xdebug.ini in your project.
Note: You only need to include the settings you want to modify in the
xdebug.remote_enable=1 xdebug.remote_host=188.8.131.52 xdebug.remote_port=9000 xdebug.remote_handler=dbgp
Include Your Custom xdebug.ini in the Build Process
When you run
nanobox run, Nanobox will build and prepare your app's runtime. You can include
extra_steps in your
boxfile.yml to run custom commands during the build process. Use an extra step to copy your custom
/data/etc/php.dev.d, the directory where development runtime configs are stored by the PHP engine.
run.config: # ... extra_steps: - cp xdebug.ini /data/etc/php.dev.d/xdebug.ini
Everything for Xdebug in the boxfile.yml
With everything for Xdebug included, this is what your
boxfile.yml will look like:
run.config: engine: php engine.config: dev_zend_extensions: add: - xdebug extra_steps: - cp xdebug.ini /data/etc/php.dev.d/xdebug.ini
With your custom
xdebug.ini in place and everything in your
boxfile.yml, start up your dev environment and your custom Xdebug configuration will be used.
# from the root of your project nanobox run
