Ah, ic, you want a <<string>> like "00001100101" - that's easy :)
Note that I do _not_ pass the array by reference here since I modify it
(using asort).
function make_a_special_bitlike_string($array)
{
$result = '';
sort($array, SORT_NUMERIC);
$max = $array[count($array)-1];
for ($i = 1; $i <= $max; ++$i) {
if (in_array($i, $array))
$result .= '1';
else
$result .= '0';
}
return $result;
}
if you need this as a number, simply return "(int)$result", but beware that
this breaks if there are more than 32 digits (highest value > 32).
