Try a bitwise and (I think the operator is '&')...
$value1 has bit 5 set? $value2 has bit 5 set?

Thanks to all those that replied. Especially Torben. (What have you been up
to?)
Miguel's solution works great.
Check out the example below:
Prints out:
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768,
Just what I wanted.
Thanks again,
Charlie

This shows all integers from 1 to 10 that have the 2 least significant
bits set:

Think back to math class when you were 14!
function isOneBit
How can I test if a number only has on bit set?
So testing different numbers will return TRUE or FALSE:
testing 0001 would return TRUE.
testing 0011 would return FALSE.
