[PHP] fletcher's checksum

[Dave Gervais]

Does anybody know how to implement the 8 and 16 bit versions of Fletcher's checksum using PHP? I hit google and came up dry. It's easy enough to find how to do it in C, but PHP if a different story.

I know there are plenty of perfectly good checksum options that are standard in PHP, but I'm forced to used Fletcher's for work.

If anybody can point me to a URL or give a code example, it would be greatly apreciated.

Best Regards,

David Gervais
