PHP Download Free – 8.4.1

Leave a Comment / Tech / By


PHP is an open source general-purpose server-side scripting language originally designed for Web development to produce dynamic Web pages. It is one of the first developed server-side scripting languages to be embedded into an HTML source document rather than calling an external file to process data. The code is interpreted by a Web server with a PHP processor module which generates the resulting Web page. It also has evolved to include a command-line interface capability and can be used in standalone graphical applications.

If you are new to PHP and want to get some idea of how it works, try the introductory tutorial.
