My first question to you is what coding languages do you currently know? Are you proficient in HTML/CSS and/or Javascript?

If you are brand new to all of this, I would focus on HTML/CSS first, at least to get the basics down.
If you are good to go in this area, then I would suggest firstly going through Programming Foundations: OOP by Simon Allardice on Lynda.com. You can sign up for a free month, knock out that course, and when you are ready to begin learning PHP, you will have an extremely sound foundation on which to build on.

But all that takes time, burns calories, and eats at time best spent elsewhere, making that mad cash. So...

Is there something in particular you need? Are you looking to build a WP plugin, or are you looking for a career?

You should learn basic php on w3schools then you can apply knowledge and practice with the framework.
