when any person request any PHP page in browser address bar

that request first go to server for example Apache is running on

that server.

then server interpret PHP files and return back response in form

of HTML. That is the reason PHP is called hypertext preprocessor

Most software you use has been compiled. This means that its computer code has been put through an application that translates it into a form your computer can understand. After a program has been compiled, it's nearly impossible to modify it or see exactly how it was created.

Open source software includes the source code along with the compiled code. People who write open source software actually encourage others to customize it

.

Cross-platform software can run on most or all systems with little or no modification
