PHP explained in a nutshell
What is PHP and what is PHP used for
PHP is the abbreviation for "PHP: Hypertext Preprocessor", a widely used and very fast to learn open source server-side scripting language, designed specifically for web development.
In the early days of the Internet, it was very difficult to create dynamic web pages that could respond to user interactions. Static HTML web pages, which were very common in the early days, became more and more exotic. However, this quickly changed, thanks in part to the PHP scripting language.
PHP was initially rather smiled at by the international developer community and not really taken seriously. One reason for this may have been the then common name for PHP "Personal Homepage Tools". It was more likely due to the limited functionality at that time and that many programming languages already mastered object-oriented programming (OOP).
PHP has now grown up and has nothing to do with "Personal Homepage Tools", the initial name of PHP. OOP has taken hold and many good and powerful PHP-Frameworks have not only significantly improved web development with PHP over the years, but also made it more professional.
