What is PHP ? How to use it ?

What is PHP?
PHP is now officially known as "PHP: HyperText Preprocessor". It is a server-side scripting language usually written in an HTML context. Unlike an ordinary HTML page, a PHP script is not sent directly to a client by the server; instead, it is parsed by the PHP binary or module, which is server-side installed. HTML elements in the script are left alone, but PHP code is interpreted and executed. PHP code in a script can query databases, create images, read and write files, talk to remote servers - the possibilities are endless. The output from PHP code is combined with the HTML in the script and the result sent to the user�s web-browser, therefore it can never tell the user whether the web-server uses PHP or not, because all the browser sees is HTML.

How to use it?
To use PHP, make a file and give it a ".php" file extension such as myfile.php.
Inside this file you can put any HTML that would normally go in a Web page. Anywhere in that file, within the HTML, you can put your PHP code (with the proper start and end PHP tags).
