PHP (a recursive initialism for PHP: Hypertext Preprocessor) is a widely-used general-purpose scripting language suited to web development.[1] It is used by over 70% of all the websites whose server-side scripting language we know.[2] Such examples include WordPress, Wikipedia, and Facebook.[3]
What Defines a PHP File?[]
A PHP file is a webpage that can contain PHP code, as well as HTML, CSS, and JavaScript code. It may include PHP functions that can process online forms, get the date and time, or access information from a database, such as a MySQL database.[4]
The PHP code within the webpage is parsed by a PHP engine on a web server, which dynamically generates HTML that is sent to the user's web browser. As a result, the user never sees the PHP code contained in the webpage, even when viewing the page source.[4]
What Can PHP Do?[]
PHP can do anything, including but not limited to: collecting form data, generating dynamic page content, managing data in databases, encrypting data, managing files on the web server, and sending and receiving cookies. However, PHP is mainly used in three areas: server-side scripting, command-line scripting, and writing desktop applications.
It can be used on all major operating systems, including Linux, Unix, Microsoft Windows, and MacOS. It can also be used with most web servers, including Apache, IIS, and others.[Citation needed]
