PHP programming language
PHP now known as “PHP Hypertext Preprocessor”, but originally “Personal Home Page Tools” is a widely used open-source programming language used primarily for server-side applications, to develop dynamic web content such as the MediaWiki software. It can be seen as an open source alternative to Microsoft’s Active Server Pages (ASP) system and to the CGI/Perl system.
Its ease of use and similarity with the most common structured programming languages, most notably C and Perl, allows most experienced programmers to start developing complex applications with a minimal learning curve. It also enables experienced developers to get involved with dynamic web content applications without having to learn a whole new set of functions and practices.
