My advice is easyway using httpd with mod_php to you,

Summary : PHP scripting language for creating dynamic web sites
URL : http://www.php.net/
License : PHP and Zend and BSD and MIT and ASL 1.0 and NCSA
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.
:
: The php package contains the module (often referred to as mod_php)
: which adds support for the PHP language to Apache HTTP Server when
: running in prefork mode.
