3. PHP
What is it?
A server-side scripting language designed specifically for the Web.
PHP code:
is embedded within HTML pages; extension is .php
is interpreted at the Web server each time the page is visited  you can only execute PHP scripts through a Web server with PHP installed!
generates (= creates on the fly) (X)HTML or JavaScript or other output that the visitor will see on the client tier
IMPORTANT: a client will never see the PHP code, only the (X)HTML that the Web server returns from the script  the browser doesn’t (need to) understand PHP (different from client-side JavaScript)!
