• WordPress is a powerful and versatile content management

system (CMS) that enables users to create and manage

websites easily. Here's an in-depth look at what WordPress is
and why it has become so popular:
• WordPress: An open-source CMS that allows users to build
and maintain websites without needing to know how to code. It
is based on PHP and MySQL and is licensed under the GPLv2
(or later).
 PHP (Hypertext Preprocessor): A widely-used open-source scripting language
that is especially suited for web development and can be embedded into HTML.
 Role in WordPress: PHP is the backbone of WordPress. It handles the server-side logic
and interacts with the database to display dynamic content on web pages.
 Functionality: When a user requests a page on a WordPress site, PHP processes the
request, retrieves the necessary data from the database, and generates the HTML content
that is sent to the user’s browser.
 MySQL: An open-source relational database management system (RDBMS).
 Role in WordPress: MySQL is used to store and manage all the data for a WordPress site.
This includes posts, pages, user information, settings, comments, and more.
 Functionality: WordPress uses MySQL queries to interact with the database. For example,
when a user publishes a new post, WordPress uses PHP to send a MySQL query to insert
the post data into the appropriate database tables
 GPLv2 License
 GPL (General Public License): A widely-used free software license that
guarantees end users the freedom to run, study, share, and modify the software.
 Version 2 (GPLv2): WordPress is licensed under the GPLv2, or any later version, which
means that it adheres to the principles of free software.
 Key Freedoms Provided by GPLv2:
 Freedom to Run the Program: Users can use WordPress for any purpose without restriction.
 Freedom to Study and Modify the Program: Users can access the source code, study how it
works, and make changes to suit their needs.
 Freedom to Distribute Copies: Users can distribute copies of WordPress to others, either as-is or
with modifications.
 Freedom to Distribute Modified Versions: Users can share their modified versions of WordPress
with others, contributing to the community and fostering collaborative improvement.
 Why These Technologies and License are Important
 PHP and MySQL:
 Accessibility: Both PHP and MySQL are open-source, making them freely available and
accessible to anyone. This lowers the barrier to entry for developers.
 Community Support: Large communities around PHP and MySQL mean abundant
resources, tutorials, and support.
 Performance: PHP is known for its performance in web development, and MySQL is
robust and efficient for managing relational databases.
 Compatibility: PHP and MySQL are widely supported by web hosting providers,
ensuring that WordPress can be easily hosted on most servers.
 History
 Founders: Matt Mullenweg and Mike Little.
 Launch Date: May 27, 2003.
 Evolution: Initially created as a blogging platform, WordPress has evolved into a
full-fledged CMS capable of powering a variety of websites, including blogs,
