Mike,
You're getting closer - but you're still passing the STRING "xFE" as the
first parameter, not a HEX value. When converted to a number for the
bit operations, the string will be converted to zero.
You need to pass a numeric value to the function.

Ah, I did not catch that since I changed the user records. It puzzled me then I remembered DUH! the
organization records. So they are now changed.
However, everything still comes back zero. A question I do have is why does the first number
(varbinary(8) in MySQL) come back hex but the second number (PHP code as
define('CERTACCESS_MEMENTRY', 0x01);) come back as decimal (or so it looks like)? Could that be the
problem?

$binanswer = $security_byte & $securitylevel_bit;

return $security_byte & $securitylevel_bit; }
