How it Works

PHP sits between your browser and the web server. When you type in the URL of a PHP website in your browser, your browser sends out a request to the web server. The web server then calls the PHP script on that page. The PHP module executes the script, which then sends out the result in the form of HTML back to your browser, which you see on the screen.
