按子数组的数量对数组进行排序

我有一个看起来像这样的数组：

Array(
   ['some_first_category'] => Array(
            ['some_first_name'] => Array(
                           [0]=>'[email protected]',
                           [1]=>'[email protected]',
                           [2]=>'[email protected]',
                           [3]=>'[email protected]' )
             ['some_second_name'] => Array (
                           [1]=>'[email protected]',
                           [2]=>'[email protected]')
             ['some_third_name'] => Array(
                           [1]=>'[email protected]',
                           [2]=>'[email protected]',
                           [3]=>'[email protected]',
                           [4]=>'[email protected]' )
   ['some_second_category'] => Array(
            ['some_first_name'] => Array(
                           [0]=>'[email protected]' )
             ['some_second_name'] => Array(
                           [1]=>'[email protected]',
                           [2]=>'[email protected]',
                           [3]=>'[email protected]',
                           [4]=>'[email protected]')
             ['some_third_name'] => Array(
                           [1]=>'[email protected]',
                           [2]=>'[email protected]'))

我想按具有名称的值的数量对数组进行排序，就我而言，我想成为这个数组：

Array(
   ['some_first_category'] => Array(
             ['some_third_name'] => Array(
                           [1]=>'[email protected]',
                           [2]=>'[email protected]',
                           [3]=>'[email protected]',
                           [4]=>'[email protected]' )
            ['some_first_name'] => Array(
                           [0]=>'[email protected]',
                           [1]=>'[email protected]',
                           [2]=>'[email protected]',
                           [3]=>'[email protected]' )
             ['some_second_name'] => Array (
                           [1]=>'[email protected]',
                           [2]=>'[email protected]')

   ['some_second_category'] => Array(
             ['some_second_name'] => Array(
                           [1]=>'[email protected]',
                           [2]=>'[email protected]',
                           [3]=>'[email protected]',
                           [4]=>'[email protected]')
             ['some_third_name'] => Array(
                           [1]=>'[email protected]',
                           [2]=>'[email protected]')
            ['some_first_name'] => Array(
                           [0]=>'[email protected]' ))

这意味着按名称值的数量（计数）对类别进行排序。有人可以帮助我吗？ 提前致谢，

所有你需要的是uasort

uasort($list, function ($a, $b) {
    $a = count($a);
    $b = count($b);
    return ($a == $b) ? 0 : (($a < $b) ? -1 : 1);
});

完整示例

$list = Array(
   'some_first_category' => Array(
            'some_first_name' => Array(
                           0=>'[email protected]',
                           1=>'secon[email protected]',
                           2=>'[email protected]',
                           3=>'[email protected]' ),
             'some_second_name' => Array (
                           1=>'[email protected]',
                           2=>'[email protected]'),
             'some_third_name' => Array(
                           1=>'[email protected]',
                           2=>'[email protected]',
                           3=>'[email protected]',
                           4=>'[email protected]' )
        ),
   'some_second_category' => Array(
            'some_first_name' => Array(
                           0=>'[email protected]' ),
             'some_second_name' => Array(
                           1=>'[email protected]',
                           2=>'[email protected]',
                           3=>'[email protected]',
                           4=>'[email protected]'),
             'some_third_name' => Array(
                           1=>'[email protected]',
                           2=>'[email protected]'))

    );

$list = array_map(function ($v) {
    uasort($v, function ($a, $b) {
        $a = count($a);
        $b = count($b);
        return ($a == $b) ? 0 : (($a < $b) ? 1 : - 1);
    });
    return $v;
}, $list);


print_r($list);
