WordPress is an open source CMS, often used as a blog publishing application powered by PHP and MySQL. It has many features including a plugin architecture and a templating system. Used by over 2% of the 10,000 biggest websites, WordPress is the most popular blog software in use today.
It was first released in May 2003 by Matt Mullenweg as a fork of b2/cafelog. As of September 2009, it was being used by 202 million websites worldwide.
WordPress has a templating system, which includes widgets that can be rearranged without editing PHP or HTML code, as well as themes that can be installed and switched between.The PHP and HTML code in themes can also be edited for more advanced customizations.
WordPress also features integrated link management; a search engine-friendly, clean permalink structure; the ability to assign nested, multiple categories to articles; and support for tagging of posts and articles. Automatic filters that provide for proper formatting and styling of text in articles are also included.
WordPress also supports the Trackback and Pingback standards for displaying links to other sites that have themselves linked to a post or article. Finally, WordPress has a rich plugin architecture which allows users and developers to extend its functionality beyond the features that come as part of the base install.
Native applications exist for Android, iPhone/iPod Touch, and BlackBerry which provide access to some of the features in the WordPress Admin panel and work with WordPress.com and many WordPress.org blogs.
# Place the WordPress files in the desired location on your web server:
* If you want to integrate WordPress into the root of your domain (e.g. http://localhost/), move or upload all contents of the unzipped WordPress directory (but excluding the directory itself) into the root directory of your web server.
* If you want to have your WordPress installation in its own subdirectory on your web site (e.g. http://localhost/blog/), rename the directory wordpress to the name you'd like the subdirectory to have and move or upload it to your web server. For example if you want the WordPress installation in a subdirectory called "blog", you should rename the directory called "wordpress" to "blog" and upload it to the root directory of your web server.
