PHP, which stands for Hypertext Preprocessor, is a widely used, open-source scripting language designed for web development. It’s embedded within HTML code, allowing you to create dynamic and interactive web pages. Think of PHP as the brain behind your website, handling everything from simple text output to complex database interactions.
Key Features of PHP:
- Server-side scripting: PHP code runs on the server, generating HTML sent to the client’s browser.

- Database compatibility: PHP integrates seamlessly with popular databases like MySQL, PostgreSQL, and SQLite.
- Large community: A vast community of developers contributes to PHP’s growth and provides support.
- Open-source: PHP is free to use and distribute.
<?php
echo "Hello, World!";
?>This simple code demonstrates the basic structure of a PHP script. The <?php tag indicates the start of the PHP code and ?> marks the end. The echo statement is used to output text to the browser.
