Overlapping binary numbers

[Anon]

I have a couple of strings, that stores binary data like this:

String 1: 100010
String 2: 101000
String 3: 001100

Is there a simple way to make each character in these strings get a 1, if there are any 1:s in that column? I would like the three examples above to overlap and turn into this:

String x: 101110

Is there a simple way to do this, or must I go through each character in every string? Because in that case i think I can code it myself.

here is a sample :

<?

$str1="100010";
$str2="101000";
$str3="001100";

echo ( $str1 & $str2 & $str3 ); // binary AND
echo ($str1 | $str2 | $str3 ); // binary OR

?>

will output
000000
101110

In your case try the second one.
