What is PHP?

More preferably known as PHP (PHP Hypertext PreProcessor), Open Source Technology for developing Dynamic Web Applications is famously known to the worldwide developer community. The endless possibilities of the PHP scripting language and a great community of users have made it one of the most popular open-source languages. For all you people living outside the UNIX world, Open Source means it doesn't cost anything. You can use it as much as you want and where you want, and nobody will ever charge you thousands of dollars for licenses and support. Even though it was originally conceived as a set of macros to help coders maintain personal home pages, its name grew a lot more from its purpose. Since then, PHP's capabilities have been extended, taking it beyond a set of utilities to a full-featured programming language, capable of managing huge database-driven online environments.

PHP is also an abbreviation and it stands, or at least used to stand, for Personal Home Page. PHP is no longer just a set of personal home page tools as it was in the beginning, but has grown to become a true programming language. Its abbreviation has gone one level deeper, and now recursively stands for "PHP Hypertext Preprocessor". But it's really known simply as PHP.
