PHP：排序一個多維陣列（$ ARR [$ i]於[ 'V']）

Question

我有在類型（UNSORTED VERSION）的數組：

<?php 
$arr['foo']['man']  = 5 ; 
$arr['foo']['str']  = 'string5' ; 
$arr['foobar']['man'] = 2 ; 
$arr['foobar']['str'] = 'string2' ; 
$arr['barfoo']['man'] = 4 ; 
$arr['barfoo']['str'] = 'string4' ; 
$arr['foofoo']['man'] = 1 ; 
$arr['foofoo']['str'] = 'string1' ; 
$arr['bar']['man']  = 3 ; 
$arr['bar']['str']  = 'string3' ; 
?> 

我想它在decending順序進行排序，同時保持該陣列中的所有其它數據，即

<?php 
$arr['foo']['man']  = 5 ; 
$arr['foo']['str']  = 'string5' ; 
$arr['barfoo']['man'] = 4 ; 
$arr['barfoo']['str'] = 'string4' ; 
$arr['bar']['man']  = 3 ; 
$arr['bar']['str']  = 'string3' ; 
$arr['foobar']['man'] = 2 ; 
$arr['foobar']['str'] = 'string2' ; 
$arr['foofoo']['man'] = 1 ; 
$arr['foofoo']['str'] = 'string1' ; 
?> 

我在PHP已經看過許多排序功能，但還沒有找到任何解決方案

任何人可以幫助我嗎？提前致謝。

Answer 1

使用此功能：

uasort($yourArray, function($a, $b) { 
    return strcmp($a['man'], $b['man']); 
}); 

還是看array_multisort
