Description:
------------
I've founded that under Linux the ~ bit operator doesn't produce
correct result;
Reproduce code:
---------------
$myvar = 0x1;
$myvar = ~$myvar;
// the result of this operation on windows system is correct
// 0xFFFFFFFE
// on Linux we have 0xFFFFFFFF
echo dechex($myvar);
Expected result:
----------------
// the result of this operation on windows system is correct
// 0xFFFFFFFE
// on Linux we have 0xFFFFFFFF
Actual result:
--------------
// the result of this operation on windows system is correct
// 0xFFFFFFFE
// on Linux we have 0xFFFFFFFF
instead of this you could use XOR operator ...
i.e. ~$myvar = $myvar ^ 0xFFFFFFFF
