Felix Geisendorfer shows, in a new blog post today, how to setup XDebug (the popular debugging extension for PHP) on a Mac OSx (or Win32/Linux) system.

One of the biggest obstacles when getting started with Xdebug was that I had a hard time finding good instructions on how to set it up on Mac OS X (I finally got rid of windows, yeah !). The only good resource I found was stored in Googles cache (wasn't live anymore) and had instructions on how to manually build xdebug from source.

His is a four step process of installing XDebug support on his MAMP setup - including a few configuration directives you'll need to apply to get XDebug support included.
