What is PHP?
If you want to become a web developer, PHP is one of the most popular programming languages you should learn. Millions of websites, blogs, business portals, and web applications are built using PHP. Even today, PHP powers a significant portion of the web because it is simple to learn, fast to develop with, and widely supported by hosting providers.
In this guide, you will learn what PHP is, how it works, where it is used, and why it is still relevant in 2026.
What is PHP?
PHP stands for PHP: Hypertext Preprocessor. It is an open-source, server-side scripting language primarily used for web development.
Unlike HTML, which is processed in the browser, PHP code runs on the web server. The server executes the PHP code and sends the generated HTML to the user’s browser.
Because of this, users never see your PHP code—they only see the final webpage.
History of PHP
PHP was created by Rasmus Lerdorf in 1994.
It started as a small collection of tools for managing personal web pages but quickly evolved into one of the world’s most widely used web development languages.
Today PHP powers countless websites, including content management systems, business applications, e-commerce stores, and custom web portals.
How Does PHP Work?
The process is simple:
- A visitor opens a PHP webpage.
- The web server receives the request.
- The PHP engine executes the code.
- PHP communicates with the database if required.
- The server generates HTML.
- The browser displays the final webpage.
This server-side execution makes PHP ideal for dynamic websites.
