(PHP Hypertext Preprocessor) A scripting language used to create dynamic Web pages. With syntax from C, Java and Perl, PHP code is embedded within HTML pages for server side execution. It is commonly used to extract data out of a database and present it on the Web page. NT/2000 and Unix Web servers support the language, and it is widely used with the mSQL database. PHP was originally known as "Personal Home Page." See mSQL.
