PHP is the most popular server-side scripting language around for doing website development. All the processing is done on the server and any HTML you want it to spit out, will get sent to the browser for display.

Server-side means PHP code runs on the server, not on the client side (browser). Javascript runs on the client-side (browser) and PHP runs on the server-side.

If you need a database, MySQL integrates extremely well with PHP, thus many developers create their dynamic websites using PHP/MySQL. A dynamic website is one in which it's content changes vs a static website where by it's content does not change. MySQL (or any database) allows you to easily change your content and thus make your site dynamic vs static.

If anyone doubts the popularity of PHP over any other server-side scripting language (.asp, ruby, python, etc.) all you have to do is look at any developers forum and count the number of posts in each server-side section. The number of posts is an indication of how active (popular) that language is. PHP's activity blows away everyone else...by far.

Php is used as object oriented programming language.

P = Personal Home Page
H = hypertext
P = Preprocessor

PHP used with MySQL is used to give a site intercativity. For example: Modern comments and replies to an article or blogpost would not be possible without PHP!
