Lesson Code: http://www.developphp.com/video/Miscellaneous/Semantic-URL-htaccess-Tutorial-SEO-Friendly-and-Clean-Links
In this video exercise we demonstrate rewriting Semantic URLs with htaccess for improved SEO and improved user experience. They are sometimes called Clean URLs, SEO friendly links, or Pretty URLs. My hope is to pass along enough insight into how it works so that everyone can customize all of their own clean URLs by themselves, no matter how many variables the system needs to take in from the URL.
