Well, to begin with applying the mask to 1101 0100 0110 0110 is
going to give you 110 not 110. But you can shift the result to the
right 4 if that is the result you want. There is no algorithm to speak
of here, just apply the mask. Like this:
$num = "1101010001100110";
$
Here's a question,
Say I have a binary number like this
1101 0100 0110 0110
And I want to pull out of the binary number the third quartet (is that the
right word)
I want to know how to apply the mask
to the number above so that the result would be
3 matches
