PHP (Hypertext Preprocessor) is a server-side scripting language widely used for web development. It was originally created by Rasmus Lerdorf in 1994 and has since evolved into a powerful and versatile scripting language. Here are some key aspects of PHP:

Server-Side Scripting: PHP is primarily used for server-side scripting, meaning the code is executed on the server rather than the client’s browser. This allows developers to create dynamic web pages by generating HTML, processing forms, managing sessions, and interacting with databases.

Embedded in HTML: PHP code is often embedded directly into HTML markup. This allows developers to seamlessly mix PHP and HTML to create dynamic content on web pages.

<html>
<body>
   <?php
      echo "Hello, World!";
   ?>
</body>
</html>
