PHP is a free scripting language, used primarily in server-side programming, command-line programming, and desktop application programming. It was developed by programmer Rasmus Lerdorf, who released his first version back in 1995. Since then, the language has been extended and refined continuously.
It is considered flexible and easy to learn, which is why it is appreciated by beginners and professionals alike. At the beginning of 2021, a full 79.2% of all websites used PHP as a server-side programming language. This puts it far ahead of all other languages. Interested parties can, for example, exchange ideas at one of the numerous PHP events that take place around the world.
