Okay, I need a reminder on this.
A given variable can consist of two constants ORd together, say TEST1 and TEST2. If I'm looking to see if one of the constants was set in the variable, I use &, right?
if(($value & TEST1) == TEST1)
{ echo 'TEST1 flag was set.'; }
if(($value & TEST2) == TEST2)
{ echo 'TEST2 flag was set.'; }
I know that works, but is that the best way? Been a while since I played with this... :)
