What is PHP?

PHP, an acronym for "PHP: Hypertext Preprocessor,", is a widely used open-source scripting language designed specifically for web development that can be embedded in HTML. Originally developed in 1994 by Rasmus Lerdorf, PHP is now one of the most commonly used languages for web development. What makes PHP special is its ability to generate dynamic content in real time. When a user visits a web page based on PHP, the PHP script is executed on the server side and the result is sent to the browser as regular HTML.
