PHP 8.3 Introduction & Server Execution
Understand how PHP executes on web servers, outputs HTML, and manages variables.
Why PHP Runs Over 77% of the Web
PHP (Hypertext Preprocessor) is a server-side scripting language designed specifically for the web. When a browser requests a .php file, the server executes the PHP code, generates standard HTML, and transmits only the resulting HTML back to the browser. The raw PHP code is never exposed to the client.
