Took a while, but I found the information that I was looking for. What I want to do was install wordpress in a subfolder (www.ammail.net/wordpress) and have the ability to run wordpress from the site root (www.ammail.net/).
To accomplish this I needed to perform the following steps. Assuming you’ve downloaded and installed or at least copied wordpress to a subfolder:
1. Edit wp-config.php to add the following configuration
// ** Hostname settings ** //
define(‘WP_SITEURL’, “http://${_SERVER['SERVER_NAME']}/wordpress”);
define(‘WP_HOME’, “http://${_SERVER['SERVER_NAME']}”);
2. Copy the index.php to the root directory and change the following line:
/** Loads the WordPress Environment and Template */
require(‘./wordpress/wp-blog-header.php’);
