NetTuts.com has posted an interview they've done with Chris Hartjes (aka "The Grumpy Programmer") about his stance on testing in PHP applications and some of his background as a developer.

Questions from Jeffery Way include:

• You recently self-published “The Grumpy Programmer’s Guide to Building Testable Applications.” What made you want to write this specific title?
• In your opinion, what is the single biggest advantage to testing your applications?
• Testing applications is a bit odd, in that, overall, the idea is a simple one. [...] Was there a specific article or video that suddenly made you “get” it all those years ago?
• What are your thoughts on the vitriol toward PHP lately - referring to various viral blog posts on the subject? Is it warranted?
