The above assumes big-endian byteorder. For little-endian use "V" instead
of "N". Or just use "L" when the file has the same byteorder as the
machine you are running this script on.
Btw, the hex() above is probably wrong. hex() converts a string into a
numeric value by intepreting it as hexadecimal. Essentially, you do it
twice resulting in:
$hex = 0xff == 255 => hex(255) == 597
Whereas:
$hex = "0xff" => hex($hex) == 255
