PHP 배열 정렬 함수 array_multisort와 uasort의 차이점

function my_sort($a, $b)
{
if ($a == $b) return 0;
return ($a > $b) ? -1 : 1;
}
$people = array("Swanson" => "Joe",
"Griffin" => "Peter", "Quagmire" => "Glenn",
"swanson" => "joe", "griffin" => "peter",
"quagmire" => "glenn");
uasort($people, "my_sort");
print_r ($people);
?>

输出结果： Array ( [griffin] => peter [swanson] => joe [quagmire] => glenn [Griffin] => Peter [Swanson] => Joe [Quagmire] => Glenn )
