Programming

I have begun to learn PHP and CSS. I already know HTML. My summer goal this year is to fully memorize/learn CSS and to get a pretty good grasp on PHP. To clarify all of this:

HTML:
Stands for: Hypertext Markup Language.
Uses: Website building, helps with customization.
Other forms: XML, Extended Markup Language.
Version: 4.0

CSS:
Stands for: Cascading Style Sheets.
Uses: Formats everything on a webpage in one place do you don't have to repeat tags (commands) over and over again.
Other forms: None
Version: 2.0

PHP:
Stands for: PHP: Hypertext Preprocessor.
Uses: Databases.
Other forms: SQL (Structured Query Language)is like PHP.
Version: 5.1

Hopefully this can help all of you with your programming/scripting languages!
