Installing Lighttpd With PHP5 And MySQL Support On CentOS 5.0 - Page 2
6 Testing PHP5 / Getting Details About Your PHP5 Installation
The document root of the default web site is /srv/www/lighttpd. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.
<?php phpinfo(); ?>

7 Getting MySQL Support In PHP5

yum search php
Pick the ones you need and install them like this:
yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
Now restart Lighttpd:
