your own function that is, everything it not premade.
this is something you have to write on your own. (should be fairly easy)

ah ok thanks! im not really asking for the exact code.. only the idea...
hehehehe... thanks so much!
actually im trying to make a rating system for toll free and local access numbers..
so the calls would be not just 5 or 6 lines but hundreds of thousands of lines.. so i really need to make the comparison the fastest way possible...
if and case statements would not be applicable.. since there would be numerous prefixes for comparison... hehehehe...
thanks!
