PHP is an open supply general-purpose server-side scripting language initially designed for Net growth to supply dynamic Net pages. It is likely one of the first developed server-side scripting languages to be embedded into an HTML supply doc slightly than calling an exterior file to course of information. The code is interpreted by a Net server with a PHP processor module which generates the ensuing Net web page. It additionally has developed to incorporate a command-line interface functionality and can be utilized in standalone graphical functions.
