Write devdocs article about PHP debugging
We have collected various bits of information in our wiki:
It would be great to transfer this to the devdocs in a more structured way, so we can perhaps include more detailed step-by-step guides for some common use cases.
I imagine getting to a place where it's easier to understand why code isn't working as expected helps newcomers to the codebase (and/or to PHP) :)
Once an article has been written, we can probably retire the current wiki page.
