Summary

This lesson provided a whirlwind tour of the PHP language, and it explained how serverside scripts are written in general. Although the syntax of other languages will differ from PHP, the basic principles for dealing with user input, processing forms, and embedding scripts in your pages will be quite similar.

In the next lesson, you'll learn how to take advantage of applications that other people have written rather than writing them yourself. Just as PHP has lots of built-in functions to take care of common tasks, so too are there many popular applications that you can download and install rather than writing them from scratch yourself.
