After tripping through (or is it slogging through) some code in different WP plugins, I started to formally go back to the beginning and started watching videos on Lynda.com. Now some of the things that I've been seeing in plugins are starting to make more sense. Maybe this approach was backwards, maybe normal, maybe it doesn't matter at all Anyway - how did you learn php/mysql? Was it formally or informally? Did you just dive in and write your own scripts first or did you slog through other people's code?
