Is that important? I don't know. I mean, where's the real data? He only
showed us the keys of a 2D array. Very weird to use salary as the 2nd key!
And, is there only one index value for each personid??

So, use uasort instead of usort:

function cmp($a, $b) {
list($k1,) = each($a);
list($k2,) = each($b);
return $k1 - $k2;
}
uasort($person, 'cmp');

Or:

$k = array_keys($person);
foreach ( $k as $i )
list($salary[$i],) = each($person[$i]);
asort($salary);
