How Backend Works Behind WordPress Website
A backend language is a programming language used to build the server-side logic of a website or application. It’s responsible for everything users don’t see but that makes everything work.
When you interact with a website (click a button, log in, submit a form), the backend language handles tasks like:
- Processing user requests
- Communicating with databases
- Handling authentication (logins, security)
- Running business logic
- Sending data back to the frontend (browser)
What is PHP?
PHP (short for Hypertext Preprocessor) is the backend programming language used to build dynamic websites and web applications. As one of the most popular programming languages, PHP is widely adopted for its simplicity, flexibility, and ability to integrate seamlessly with databases, making it a cornerstone of modern web development.
