WordPress - Free Open Source Blogging Tool and a Content Management System (CMS)
WordPress is a Free Open Source Blogging Tool and a Content Management System (CMS) based on PHP and MySQL, which runs on a web hosting service. Features include a plug-in architecture and a template system.
WordPress has a web template system using a template processor.
- Themes: WordPress users may install and switch between themes. Themes allow users to change the look and functionality of a WordPress website or installation without altering the information content or structure of the site. Themes may be installed using the WordPress "Appearance" administration tool or theme folders may be uploaded via FTP. The PHP, HTML & CSS code found in themes can be added or edited for providing advanced features. Thousands of WordPress themes exist, some free, and some premium (paid for) templates.
- Plugins: One very popular feature of WordPress is its plugin architecture which allows users and developers to extend its abilities beyond the core installation. WordPress has a database of over 26,000 plugins, each of which offers custom functions and features enabling users to tailor their sites to their specific needs. These customizations range from SEO (Search Engine Optimization) enhancers, to client portals used to display private information to logged in users, to content displaying features, such as the addition of widgets and navigation bars.
- Multi-user and Multi-Blogging: Prior to WordPress 3.0, WordPress supported one blog per installation, although multiple concurrent copies may be run from different directories if configured to use separate database tables. WordPress Multi-User (WordPress MU, or WPMU) was a fork of WordPress created to allow multiple blogs to exist within one installation but is able to be administered by a centralized maintainer. WordPress MU makes it possible for those with websites to host their own blogging communities, as well as control and moderate all the blogs from a single dashboard. WordPress MU adds eight new data tables for each blog. As of the release of WordPress 3.0, WordPress MU has merged with WordPress.
- Mobiles: Native applications exist for WebOS, Android, iOS (iPhone, iPod Touch, iPad), Windows Phone, and BlackBerry. These applications, designed by Automattic, allow a limited set of options, which include adding new blog posts and pages, commenting, moderating comments, replying to comments in addition to the ability to view the stats.
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 are also included, providing standardized formatting and styling of text in articles (for example, converting regular quotes to smart quotes). WordPress also supports the Trackback and Pingback standards for displaying links to other sites that have themselves linked to a post or article.
The following is a list of some of the features that come as standard with WordPress, however there are literally thousands of plugins that extend what WordPress does, so the actual functionality is nearly limitless.
- Simplicity Simplicity makes it possible for you to get online and get publishing, quickly. Nothing should get in the way of you getting your website up and your content out there. WordPress is built to make that happen.
- Flexibility With WordPress, you can create any type of website you want: a personal blog or website, a photoblog, a business website, a professional portfolio, a government website, a magazine or news website, an online community, even a network of websites. You can make your website beautiful with themes, and extend it with plugins. You can even build your very own application.
- Publish with Ease If you've ever created a document, you're already a whizz at creating content with WordPress. You can create Posts and Pages, format them easily, insert media, and with the click of a button your content is live and on the web.
- Publishing Tools WordPress makes it easy for you to manage your content. Create drafts, schedule publication, and look at your post revisions. Make your content public or private, and secure posts and pages with a password.
- User Management Not everyone requires the same access to your website. Administrators manage the site, editors work with content, authors and contributors write that content, and subscribers have a profile that they can manage. This lets you have a variety of contributors to your website, and let others simply be part of your community.
- Media Management They say a picture says a thousand words, which is why it's important for you to be able to quickly and easily upload images and media to WordPress. Drag and drop your media into the uploader to add it to your website. Add alt text, captions, and titles, and insert images and galleries into your content. We've even added a few image editing tools you can have fun with.
- Full Standards Compliance Every piece of WordPress generated code is in full compliance with the standards set by the W3C. This means that your website will work in today's browser, while maintaining forward compatibility with the next generation of browser. Your website is a beautiful thing, now and in the future.
- Easy Theme System WordPress comes bundled with two default themes, but if they aren't for you there's a theme directory with thousands of themes for you to create a beautiful website. None of those to your taste? Upload your own theme with the click of a button. It only takes a few seconds for you to give your website a complete makeover.
- Extend with Plugins WordPress comes packed full of features for every user, for every other feature there's a plugin directory with thousands of plugins. Add complex galleries, social networking, forums, social media widgets, spam protection, calendars, fine-tune controls for search engine optimization, and forms.
- Built-in Comments Your blog is your home, and comments provide a space for your friends and followers to engage with your content. WordPress's comment tools give you everything you need to be a forum for discussion and to moderate that discussion.
- Search Engine Optimized When the head of Google's web spam team says that WordPress is a great choice, taking care of 80-90% of the mechanics of search engine optimization for you, you know you're on to a good thing. For more fine-grained SEO control, there are plenty of SEO plugins to take care of that for you.
- Multilingual WordPress is available in more than 70 languages. If you or the person you're building the website for would prefer to use WordPress in a language other than English, that's easy to do.
- Easy Installation and Upgrades WordPress has always been easy to install and upgrade. If you're happy using an FTP program, you can create a database, upload WordPress using FTP, and run the installer. Not familiar with FTP? Plenty of web hosts offer one-click WordPress installers that let you install WordPress with, well, just one click!
- Importers Using blog or website software that you aren't happy with? Running your blog on a hosted service that's about to shut down? WordPress comes with importers for blogger, LiveJournal, Movable Type, TypePad, Tumblr, and WordPress. If you're ready to make the move, we've made it easy for you.
- Own Your Data Hosted services come and go. If you've ever used a service that disappeared, you know how traumatic that can be. If you've ever seen adverts appear on your website, you've probably been pretty annoyed. Using WordPress means no one has access to your content. Own your data, all of it - your website, your content, your data.
- Freedom WordPress is licensed under the GPL which was created to protect your freedoms. You are free to use WordPress in any way you choose: install it, use it, modify it, distribute it. Software freedom is the foundation that WordPress is built on.
- Community As the most popular open source CMS on the web, WordPress has a vibrant and supportive community. Ask a question on the support forums and get help from a volunteer, attend a WordCamp or Meetup to learn more about WordPress, read blogs posts and tutorials about WordPress. Community is at the heart of WordPress, making it what it is today.
- Contribute You can be WordPress too! Help to build WordPress, answer questions on the support forums, write documentation, translate WordPress into your language, speak at a WordCamp, write about WordPress on your blog. Whatever your skill, we'd love to have you.
For developers, we've got lots of goodies packed under the hood that you can use to extend WordPress in whatever direction takes your fancy.
- Plugin System The WordPress APIs make it possible for you to create plugins to extend WordPress. WordPress's extensibility lies in the thousands of hooks at your disposal. Once you've created your plugin, we've even got a plugin repository for you to host it on.

- Application Framework If you want to build an application, WordPress can help with that too. Under the hood WordPress provides a lot of the features that your app will need, things like translations, user management, HTTP requests, databases, URL routing and much, much more.
- Custom Content Types WordPress comes with default content types, but for more flexibility you can add a few lines of code to create your own custom post types, taxonomies, and metadata. Take WordPress in whatever direction you wish.
