Not sure where you can read more, but let me try to explain it. The bitwise operators operate on a binary representation of a number. 4 is 100 in binary, 5 is 101. 5 | 4 results in 5, because the | operator sets bits set in either number. 5 & 4 results in 4, because the & operator only sets bits set in both. As for 4 & 4, the same bits are set in both 4 and 4 (since they're the same number! :)), so it results in the same number.

Hi James,
& is a bit-wise AND. && is a logical AND. The bitwise AND will return
a number, the logical AND will return true or false boolean values. It's a subtle distinction, but important. 4 & 4 == 4 4 && 4 == true

Ok, this may have already been posted to the list already, but the archives don't seem to like the & and && characters.
I'm running into some code that looks like this:
<snip> Define('INPUT', 2); <snip> if($search->level & INPUT) $tmp.= $search->input();
Ok, what's the & mean?
As far as I could tell from the very little documentation I was able
to scrape up on google, & is a bit-by-bit operator. Thus, if either INPUT or $search->level, we get TRUE... If that's the case, what's the
point of using it instead of || ?
Or, do I just totally not understand the point of this. Thanks
