What is PHP?

Server-Side Scripting Powerhouse

PHP (Hypertext Preprocessor) is a popular open-source server-side scripting language designed specifically for web development. Created by Rasmus Lerdorf in 1994, it has grown into one of the most widely used languages for building dynamic websites and applications.


PHP seamlessly integrates with HTML, allowing developers to embed server-side logic directly into web pages. It excels at handling forms, databases, sessions, authentication, and generating dynamic content.
