What is PHP?
The term PHP is an acronym for Hypertext Preprocessor. PHP is a widely-used, server-side scripting language designed specifically for web development.
Websites like www.facebook.com, www.yahoo.com are also built on PHP.
One of the main reasons behind this is that PHP can be easily embedded in HTML files and HTML codes can also be written in a PHP file.
