Here's the article summary:
aPaddedCell wrote: A debugger helps greatly when testing or bug fixing in PHP, when working with complicated code, or fixing difficult problems: a debugger is an invaluable tool. This article shows how to set up a PHP debugger in Ubuntu (tested on both Feisty 7.04 and the upcoming Gutsy 7.10) using Xdebug and Vim. This is aimed at developers who may be good at coding but are not necessarily familiar with GNU+Linux in general, therefore everything is explained simply and step-by-step.
Post any comments, suggestions, questions etc. here. Hope you find the article useful.

Personally, I would explain how to copy/paste using the keyboard and middle mouse button. I know you were trying to make it easy for everyone, but every programmer should know basic keyboard functions.

Good suggestion. I added a note that ctrl-c and ctrl-v can be used just the same as other operating systems. Didn't want to over-explain it or patronise anyone so have kept it short.
Thanks for that.

Well, I think that you shouldn't have to explain how to copy and paste at all. Just say Copy and Paste. Everyone knows how to do that, unless you're a complete and total noob, in which case you shouldn't be attempting to debug PHP in Ubuntu. Or using PHP at all for that matter
Being fussy though - good article

I think you should also include
xdebug.show_exception_trace=on
in your sample config
otherwise, xdebug doesn't display stack traces for uncaught exceptions.
