PHP

I only know PHP is the most commonly used server side language, and if you plan on doing anything more than just a plain jane website - you better know PHP. I haven't learned it yet...looking forward to it this semester.
 I've had my eye on these links:

1. W3Schools PHP
2. The New Boston PHP Video Tutorials 200 free PHP video tutorials!
3. Code Academy - Learn PHP

About Intro to Internet Computing

  As a computer science major, Intro to Internet Computing is the most practical course I have taken yet.  The course's assignments are a series of projects building different types of websites, each using a different web development technology required by many employers in our field.  I have started a portfolio website with some projects I completed in past semesters, so I am excited to have these projects to work on this semester and add to the site.  The link is on the left hand side.  Intro to Internet Computing will cover subjects such as HTML5, CSS3, JavaScript, PHP, MySQL, and AJAX.  I have an intermediate knowledge of HTML5, CSS3, JavaScript, and AJAX; but I have never used PHP and MySQL.
