Simple as this

$array = array(2 => 2, 1 => 8);

$output['present'] = $array[2];
$output['absent'] = $array[1];

print_r($output);

If it's a multi-dimensional array of absents and presents

$array = array(
    array(2 => 2, 1 => 8),
    array(2 => 3, 1 => 7)
);

foreach ($array as $value) {
   $output[] = array('present' => $value[2], 'absent' => $value[1]);
}

print_r($output);

$res = array_combine(array('present', 'absent'), 
                array_values(array(2 => 2, 1 => 8)));
print_r($res);
