This is a strange request but here you go.
function CRC8bit($data){
return (crc32($data) & 255);
}

Subject: [PHP] 8 bit check sum???? Not 32 bit
Hello all,
I currently have a perl subroutine that uses an 8 bit check sum. From
what I have found, in books and the site, php will only do 32 bit.
Here is what I have currently
sub _hash_domain {
return uc(
unpack('H2',
pack('C',
unpack("%8C*", shift)
)
)
);
}
This works fine in perl but I would like to get this to work in PHP What
am I missing.
Thanks for you help
Brian C. Doyle
