I’ve just finised writing a 5 card hand evaluator (I’m avoding the ‘pkr’
word since the spam filter won’t let me post when I use that word),
using the algorithm found: http://www.suffecool.net/*/evaluator.html (<<
replace * with the ‘pkr’ word, same in the next link >>).
You can download it from here:
Use the ‘eval’ method. For the purposes of this code a card is defined
as an array where element  is a number 0…12 (0 = two, 1 = three …
11 = king, 12 = ace) and element  is a number 0…2 (0 = clubs, 1 =
diamonds, 2 = hearts, 3 = spades).
The lower the value returned, the higher-ranking the hand. Enjoy.
