Whoah. The lack of support for > 32 bit integers is really a pain for some things. Anyway, for
bitwise operations requiring a > 32 bit number:
($big42bitInteger & $someSmallInteger)
You can move to mysql or some other db if you're using one anyway:
select id,($big42bitInteger & $someSmallInteger) as isBitwiseAND FROM someTable;
if ($row->isBitwiseAND > 0) {
do stuff;
}
