19. WordPress is Blog Software
a CMS
Content
Management
System
#memtech

20. Why use a CMS?
When you have a lot of content,
managing it becomes very complex.
CMS's make things simpler.
• Content lives in the database.
• The "look" of the website lives in the theme/template.
• The CMS brings the two together, in real-time.

21. WordPress is written in PHP
PHP is a language designed for the web
• Native HTML support
• Has functions to do the types of things web pages do
• Actively being developed
• Works on any platform
• Works with any webserver software (apache, nginx, litespeed)
PHP is easy to learn, if you ever needed to do so.

42. Plugin API
Actions and Filters
(the missing part of PHP)
Actions let you hook your own code into defined points of page
generation.
Filters let you modify specific useful variables at specific points,
such as return values from WordPress core functions.

44. Object Oriented Programming
(well... almost...)
WordPress has historically been written with mostly procedural
code.
However, with WordPress 3.0, and the new PHP 5.2 requirement,
WordPress is rapidly evolving to include classes and objects for
more and more aspects of the core code base.
(Procedural code still works fine though, if that's more your
style...)
