What is different between php and html language

Answer 1

HTML is a language used to describe to a browser how to display text and other objects in a browser window. It is not a programming language. HTML works on a client computer (the system on which the page is being viewed). 
PHP is a scripting language, and can be used to create web pages written in HTML. PHP runs on the server (the system from which the page comes), and is a full-fledged programming language.
