See ksort and uksort.

Here's a working example:

 2, 'one' => 1, 'three' => 3);
print_r($data);
ksort($data);
echo "ksort:\n";
print_r($data);
uksort($data,'cmp');
echo "uksort:\n";
print_r($data);
function cmp($a, $b)
{
    $num=' one two three four five six seven eight nine ten';
    $ai = stripos($num,$a);
    $bi = stripos($num,$b);
    if ($ai>0 && $bi>0) {
        return ($ai > $bi) ? 1 : -1;
    }
    return strcasecmp($a, $b);
}

Output:

Array
(
    [two] => 2
    [one] => 1
    [three] => 3
)
ksort:
Array
(
    [one] => 1
    [three] => 3
    [two] => 2
)
uksort:
Array
(
    [one] => 1
    [two] => 2
    [three] => 3
)
