Web development is a very specific, yet demanded kind of work nowadays. The choice of the programming language is the very first step in the development of any project. It depends on such factors as budget, purpose, scale. Although, some programming languages are used fairly more often than others. Despite being old, PHP remains the most often used programming language for the back-end. About 80% of all websites including ones everyone uses on a daily basis are made with PHP. And this percentage isn’t going to reduce anytime soon.
