php|tropics Design Patterns Presentation
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 fo Chris Shiflett’s Security presentation (which we all know how that one drew a crowd at php|works in Toronto last fall).
