PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. As of January 2013, PHP was installed on more than 240 million websites (39% of those sampled) and 2.1 million web servers.
PHP is neither real programming language-but PHP lets you use so-called scripting in your documents. To describe what a PHP page is, you could say that it is a file with the extension .php that contains a combination of HTML tags and scripts that run on a web server.
