If you aren't extremely well versed in PHP yet you might want to consider starting with Python or even node.js. They're growing much faster than PHP at the moment.
Well PHP is the only one I've had a bit of background in compared to others, and it coupled well with Dreamweaver / XAMPP for local host testing. It's not hard, it's just looking up methods which fit my needs to accomplish a certain task.
This might be just what it takes for me to get started with Python.
