PHP: Xdebug in PHPStorm on, almost, all docker environments, is easy
Xdebug is a very powerful debugging tool, well actually, probably the God tool of all tools if you're debugging.
It lets you pause the execution of your app and lets you analyze, in full context what is happening, step debug etc etc.
Even though the setup has gotten drastically easier, thanks to the awesome effort Derick Rethans, its creator, has put in it, it still appears to scare of some developers... Let us hope this DevNote helps.
