Answer 1

I recently used the following in an application that is working well for my needs.

.htaccess

# enable rewrite engine
RewriteEngine On

# if requested url does not exist pass it as path info to index.php
RewriteRule ^$ index.php?/ [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php?/$1 [QSA,L]

index.php

foreach (explode ("/", $_SERVER['REQUEST_URI']) as $part)
{
    // Figure out what you want to do with the URL parts.
}
