Summary : PHP scripting language for creating dynamic web sites
Description :
PHP is an HTML-embedded scripting language. PHP attempts to make it
easy for developers to write dynamically generated web pages. PHP also
offers built-in database integration for several commercial and
non-commercial database management systems, so writing a
database-enabled webpage with PHP is fairly simple. The most common
use of PHP coding is probably as a replacement for CGI scripts.
