PHP Role in Web Development

PHP LogoA lot of non-technical people thinks that PHP is everything used in web development. But, that is not the case.

PHP is only a bridge between data and presentation layer. The presentation layer is HTML and CSS. The data can be text, numbers images or binary data stored in database or as a file.

PHP acts as a transport and processing between data and presentation.

The presentation layer is naturally something that the user sees. A User Interface is perhaps a better description for it.

Of course, with mobile taking over the web browser, the presentation layer is now native to the mobile platform. It can be Android, iOS or Windows.

PHP will remain relevant for quite a long time.
