PHP programming language, a quick tour

PHP is a popular general-purpose scripting language that is especially suited to web development.

PHP stands for "PHP: Hypertext Preprocessor". The main goal of the language is to allow web developers to write dynamically generated web pages quickly.1

The PHP official website documentation says about other applications of PHP programming language, besides web development. BTW, nowadays we know that using PHP in these OTHER applications are not realistic, or at least are not the popular applications of PHP.

PHP dominates web development these days (at the beginning of 2022). The statistics show near 80 percent of websites are developed with PHP. But being more precise, this market share could go down when we consider top websites on the web. In fact, for the top 1000 websites on the web, its usage goes down to near 60 percent (but remains a=the main player in the market). 2

Even for top 1000 websites, the next player is ASP.net with near 20 percent websites! It shows how PHP dominates the current web.
