Seriously learning PHP for real. I've been tweaking around in it for years, but now it's time to get serious.
One of my favorite reference sites, W3 Schools offers all course/tutorial information free online. To get certified in a particular area, it's only $95. I don't know if it matters much to say I'm certified, but I may consider it when I have 1337 skills in PHP. I did very well with their mini HTML & CSS quizzes, and perhaps after I've learned more in PHP I may feel inspired to have all those fancy "Certified in" badges on my site. I don't know. I guess it depends on whether my clients think it's important or not. Hmm...
