PHP Website

We use PHP to hide E-Mail addresses as the HTML MAILTO: feature that can be tracked by SPAM BOTS (robots that send junk through email) is a serious problem.
PHP is also the best way to make shopping carts on e-commerce websites.
Without PHP, the web would still look like it did in 1992.
PHP is mainly focused on server-side scripting, so you can do anything any other CGI program can do, such as collect form data and generate dynamic page content.
