Introduction to PHP

PHP is a general-purpose and powerful scripting language to produce dynamic web site and interactive web pages. PHP is free software, used by many as an efficient alternative to Microsoft Active Server Pages (ASP). PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. As of press time, PHP installed on more that 20 million websites and 1 million web servers.

PHP originally stood for "Personal Home Page" when it was first conceived and created by danish Rasmus Lerdorf, it is now said to stand for "PHP: Hypertext Preprocessor". Names such as these are called recursive acronyms. They refer to themselves within the meaning of the expression or abbreviation, a common practice in the IT industry.
