What is PHP? And what it needs to work on it

PHP: Hypertext Preprocessor
PHP is independent of the platform, which means it works the same as in Windows, Linux, Unix, Mac OS X, etc. PHP supports a database set. PHP is free, highly populated, with open sources. PHP scripts run on the server. PHP is compatible with any modern server, such as Apache, IIS, etc...

A shortlist of what PHP can do:
-Generating the content of dynamic pages.
-Creating, opening, reading, writing, deleting, and closing files on the server.
-Collection of data from questionnaires.
-Adding, deleting, and modifying the information in the database.
-User access control.

-and much more!

• What does it take to work?

In advance, to work we need basic HTML knowledge. PHP can work in the core of WordPress, the simplest system of building a blog on the web. Moreover, PHP runs on Facebook's servers, the largest social networking web.

To use PHP, the first step is to install a web server on the PC, then install PHP. The simplest way is to install a program called XAMPP. It includes Apache, MySQL, and PHP, and is free. XAMPP can be downloaded and installed from www.xampp.org. Open the XAMPP Control Panel and start the Apache webserver.

The only thing you need to work with PHP is a basic text editor.
