active record not working need help!!!!

hello all,
I'am learning codeigniter and i have come across a problem, I have this tutorial that explains CI active records but when i load up the page in my browser i get a 404 page not found error message. The only difference that i can point to is that in the tut the use PHP server and i use XAMMP, i personally don't think that is the problem, i think there is something missing but i don't know what! the tutorial is here 

What i also tried is moving the CI folder to the document root (in linux home/documents/projects/website1) and tried the php server i got the same result 404 page not found error message
