What is php?

PHP is a computer language that helps make websites come alive.

Think of it like this:

• HTML builds the structure of a page (like walls of a house).
• CSS makes it look nice (like paint and decorations).
• PHP makes the page do stuff — like showing your name after you log in, saving a comment you post, or showing new products automatically.

It runs on the web server, which means it works behind the scenes before the page reaches your screen.

If you’ve ever used a website that changes when you click something, log in, or fill out a form — there’s a good chance PHP helped make that happen.
