The latest post from the SitePoint PHP blog, a new tutorial by Peter Nijssen, shows you how to get started with Xdebug and Sublime Text 3 to debug your PHP applications.

Debugging – we all do it a lot. Writing code perfectly the first time around is hard and only a few (if any) succeed at it. More than a year ago, Shameer wrote an article on SitePoint about how you can debug your application using Xdebug and Netbeans. In this article, we are going to have a look at how we can debug using Xdebug in combination with Sublime Text.

He assumes you already have Xdebug installed (and links to the instructions for those that don't) and helps you configure it to find your listening editor. Back in Sublime, he shows you how to use the package manager to install the Xdebug client and configure the current project to use it. He shows how to set up breakpoints and view the stack/watch data when the point is hit.
