Introduction to PHP
PHP is a widely used open-source scripting language designed for web development. It runs on the server and is used to create dynamic and interactive web pages.
PHP is especially popular for backend development because it integrates easily with databases like MySQL and works well with HTML to build complete web applications.
What is PHP
PHP stands for Hypertext Preprocessor. It is executed on the server, and the result is sent to the browser as plain HTML. This allows developers to build dynamic websites that can handle user data, sessions, and real-time updates.

How PHP Works
When a user requests a PHP page, the server processes the PHP code and generates HTML. This HTML is then sent to the user’s browser, where it is displayed as a normal web page.
Unlike frontend languages, PHP code is not visible to users because it runs on the server.
Basic PHP Syntax
PHP code is written inside special tags:
echo “Hello, World!”;
?>
The echo statement is used to display output on the screen.
