PHP scripting language
PHP (Hypertext preprocessor) is a popular scripting language used for building web pages. It is very easy to learn, and once you get to know it, you can accomplish a lot with it. When a user visits your PHP pages, your web server will automatically process PHP code which will help determine what exactly to show to the user.
Everything else, such as mathematical operations, file operations, variables, etc., is not going to be displayed to the user, which means that the user will only see generated HTML page in his browser, without the PHP code.
The major part of the syntax is taken from the languages C, Java, and Perla, and created with a few specific and unique functions. The purpose of this language is to quickly write dynamically generated pages.
In order to be able to use your PHP script or the page with a PHP code, your web server needs to support PHP. The majority of commercial servers support it, as well as a smaller number of free servers.
If you want to try out some PHP scripts on your computer, there is a solution for that: download and install the Xammp programme.
