I think the goofy variable is getting truncated....
(3FFF | 4) is returning 7
(4FFF | 4) is returning 8

looks like it's trying to treat $cap1 as a decimal number, and not a hex
number
have a look at this:
for ($cap = 0; $cap < 64; $cap++)
{
$cap1 = dechex($cap);
$bit = ($cap1 | 0x01);
echo "$cap - $cap1 - $bit\n";
}
and you'll see what I mean...

Ugggg... Does anybody know why this doesn't work...
Example:
$cap = 16383;
$cap1 = dechex($cap);
// cap1 is now equal to 3FFF;
$bit = ($cap1 | 0x01);
//bit should equal 3FFF, but it doesn't.. it is always = 3 !!
