PHP INTRODUCTION

What is PHP?

PHP “Hypertext Preprocessor” is a programming language that’s used mostly for building websites. Instead of a PHP program running on a desktop computer for the use of one person, it typically runs on a web server and is accessed by lots of people using web browsers on their own computers.

PHP is a programming language. Something in the web server computer reads your PHP programs, which are instructions written in this programming language, and figures out what to do. The PHP engine follows your instructions. Programmers often say “PHP” when they mean either the programming language or the engine. “PHP” means the programming language. “PHP engine” means the thing that follows the commands in the PHP programs you write and that generates web pages.
