PHP (Hypertext Preprocessor) is a server-side scripting language designed specifically for web development. It's widely used to create dynamic web pages and web applications.

Key Features of PHP:

• Server-side: Code runs on the server, and the result (usually HTML) is sent to the client's browser.

• Open-source: Free to use and supported by a large community.

• Embedded in HTML: You can write PHP code directly inside an HTML file using <?php ... ?> tags.

• Works with databases: Commonly used with MySQL or MariaDB to build data-driven websites (like WordPress).

• Cross-platform: Runs on different operating systems like Windows, Linux, and macOS.
