How to use xdebug in Magento 2?

@edmond_brakus 

To use xdebug in Magento 2, you will need to have xdebug installed and enabled in your PHP environment. You can check if xdebug is installed by running the following command from the command line:

php -m | grep xdebug

If xdebug is not installed, you can install it by following the instructions for your specific operating system. Once xdebug is installed, you will need to configure it in your PHP configuration file (php.ini).

To enable xdebug in Magento 2, you will need to add the following lines to your PHP configuration file:

zend_extension=xdebug.so xdebug.remote_enable=1 xdebug.remote_host=localhost xdebug.remote_port=9000 xdebug.remote_handler=dbgp

Once xdebug is enabled, you can use a debugger tool such as Eclipse, NetBeans, or PHPStorm to connect to the xdebug service and debug your Magento 2 code.

In Eclipse or NetBeans, you can set breakpoints in your code and use the debugger to step through the code and examine variables as it is executed. In PHPStorm, you can use the built-in debugger to do the same.

To start debugging in Eclipse or NetBeans, you will need to run the Magento 2 application in "Debug" mode and then use the debugger to connect to the xdebug service. In PHPStorm, you can start debugging directly from the IDE.

I hope this helps! Let me know if you have any questions.
