Answer 1

asort/を使用できるはずですarsort。arsortPHP.net からの使用例( http://www.php.net/manual/en/function.arsort.php ):

<?php
    $fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
    arsort($fruits);
    foreach ($fruits as $key => $val) {
        echo "$key = $val\n";
    }
?>

Answer 2

PHPマニュアルから直接来ます

This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant.

<?php
$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple");
asort($fruits);
foreach ($fruits as $key => $val) {
    echo "$key = $val\n";
}
?>
