PHP is a scripting language originally designed for producing dynamic web pages. PHP generally runs on a web
server, taking PHP code as its input and creating web pages as output. It can also be used for command-line scripting
and client-side GUI applications. PHP can be deployed on most web servers, many operating systems and platforms,
and can be used with many relational database management systems. It is available free of charge, and the PHP
Group provides the complete source code for users to build, customize and extend for their own use.

Originally designed to create dynamic web pages, PHP's principal focus is server-side scripting,[35] and it is similar to
other server-side scripting languages that provide dynamic content from a web server to a client, such as Microsoft's
ASP.NET system, Sun Microsystems' JavaServer Pages,[36] and mod_perl. PHP has also attracted the development
of many frameworks that provide building blocks and a design structure to promote rapid application development
(RAD). Some of these include CakePHP, PRADO, Symfony, CodeIgniter, and Zend Framework, offering features
similar to other web application frameworks.
