What Is PHP? | Definition of PhP. | Introduction of Php. Language

PHP is a language that has outgrown its name. It was originally conceived as a set
of macros to help coders maintain personal home pages, and its name grew 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.
As PHP's capabilities have grown, so too has its popularity. According to NetCraft
(, PHP was running on more than 1 million hosts in
November 1999. As of February 2000, that figure had already risen to 1.4 million
hosts. According to E-Soft, PHP is the most popular Apache module available,
beating even ModPerl.
PHP is now officially known as PHP: HyperText Preprocessor. It is a server-side
scripting language usually written in an HTML context. Unlike an ordinary HTML
page, a PHP script is not sent directly to a client by the server; instead, it is parsed
by the PHP binary or module. HTML elements in the script are left alone, but PHP
code is interpreted and executed. PHP code in a script can query databases, create
images, read and write files, talk to remote servers
the possibilities are endless.

The output from PHP code is combined with the HTML in the script and the result
sent to the user.
