Jason Sweat has posted both sets of slides from his php|tropics talks:

Here is the Test Driven Development in PHP presentation from php|tropics. You can download either the zip or tarball flavors. In each is the PowerPoint presentation and the code files with unit tests I used when writing the presentation. This presentation also went well. I went out on a bit of a limb and did some TDD live for about 45 minutes near the end of the session. We all decided to work on a MySQL driven Guestbook.

Here is the Design Patterns in PHP5 presentation from php|tropics. You can download either the zip or tarball flavors. In each is the PowerPoint presentation and the code files with unit tests I used when writing the presentation. I felt this talk went fairly well, particularly considering it was in the same time slot as part two of Chris Shiflett’s Security presentation (which we all know how that one drew a crowd at php|works in Toronto last fall).

I didn't get a chance to attend either of these sessions (I was taking the Zend Cert Exam during one), but I heard nothing but good things about them. The gave several examples, including the Factory and Singleton approaches. It's a good talk for an intro to patterns (for anyone looking), and, thankfully, he also includes all the source code examples for each of the patterns highlighted...
