fwPack/fwUnpack in php?

[Frank Leahy]

I'm successfully using fwPack and fwUnpack to store passwords in a 
preferences file -- thank you Richard!

Has anyone ported this code to php by chance?  I was about to do it, 
but figured if it had already been done I'd save a 1/2 a day.

I'd be willing to trade Transcript code that read JPEG files and get 
height, width, and other info -- everything except EXIF (almost 
working).

Thanks,
-- Frank
