Chapter 1. Orientation and First Steps
There are lots of great reasons to write computer programs in PHP.
Maybe you want to learn PHP because you need to put together a small
web site for yourself that has some interactive elements. Perhaps PHP
is being used where you work and you have to get up to speed. This
chapter provides context for how PHP fits into the puzzle of web site
construction: what it can do and why it's so good at
what it does. You'll also get your first look at the
PHP language and see it in action.
