What is PHP?

PHP (Hypertext Preprocessor) is a server-side scripting language used to create dynamic and interactive websites.
It runs on a web server and is widely used for web development.

Explanation:

• <?php ... ?> → PHP code block
• echo → used to print text or data(PHP functions not case sensitive).
• Output will be Hello, World! on your web page.
• In PHP, keywords (e.g. if, else, while, echo, etc.), classes, functions, and user-defined functions are not case-sensitive.
