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 (

And get_difference should have used abs() as discussed in the forum ;)
