排序數組由值，那麼關鍵

Question

我使用asort對簡單數組：

$arr = array('A'=>30, 'B'=>12, 'K'=>23, 'X'=>1, 'H'=>11, 'T'=>1, 'U'=1); 

asort($arr) 

產生

Array 
(
    [A] => 30 
    [K] => 23 
    [B] => 12 
    [H] => 11 
    [X] => 1 
    [T] => 1 
    [Z] => 1 
) 

是否存在被價值和一個鍵按本機方式調用（同時保留鍵/值關係）？

例如，我想我的結果落得這樣的：

Array 
(
    [A] => 30 
    [K] => 23 
    [B] => 12 
    [H] => 11 
    [T] => 1 
    [X] => 1 
    [Z] => 1 
) 

Answer 1

機功能沒有，但也有一些方法可以做到這一點很容易

PHP array multiple sort - by value then by key?

Answer 2

<?php 
$arr = array('A'=>30, 'B'=>12, 'K'=>23, 'X'=>1, 'H'=>11, 'T'=>1, 'U'=>1); 

Function ArrSort ($Array){ 
    $tag = array(); 
    $num = array(); 

    foreach($Array as $key => $value){ 
     $tag[] = $key; 
     $num[] = $value; 
    } 
    array_multisort($num, SORT_DESC, $tag, SORT_ASC, $Array); 
    return $Array; 

} 

print_r(ArrSort($arr)); 
?> 

輸出：

Array 
(
    [A] => 30 
    [K] => 23 
    [B] => 12 
    [H] => 11 
    [T] => 1 
    [U] => 1 
    [X] => 1 
)
