Compare Ratings, and Return Similar Tastes

Lets say you have 5 books... and 5 people rate each of those books. Now you want to find out who's interests, based on each users 5 ratings, are similar to who?

That's what this algorithm calculates.

Similar to the Euclidean algorithm, or as though i have been told.

Hi ya gunni, It's nice to get a comment saying "Very nice code! Very readable." after 4 months of not writing much advanced code (taking it easy cus of my hands problem). So hey, not lost the ability to code... yet!!! lol I actually didn't know about the abs function... not so sure why i didn't use array_slice though, sure there was a reason at the time :-S fortunately can't remember now though. Thanks for taking the time to comment. Kind regards, Scott

Very nice code! Very readable. Your function get_matches should have used array_slice ( [url]http://www.php.net/manual/de/function.array-slice.php[/url] ), though. And get_difference should have used abs() as discussed in the forum ;)
