How Does PHP Work?
When someone visits your PHP webpage, your web server processes the PHP code. It then determines which parts it needs to show to visitors.

This means that PHP is a powerful behind the scenes scripting language that your visitor’s wont see.

?>. This reduces the amount of html commands being used and also reduces the time it takes for a user to create a website.
