集合：：组合Cakephp，使用一维数组创建多维数组

我有一个数组，对于相同键的数组，相同值有多个值

例如

我想使用Cakephp中的Set:：Combine将它们转换为如下所示的年龄

Array(
   [20] => Array(
                 [0] => Array(
                             'name' => "Bob",
                             'age'  => 20,
                             'marks'=> 50
                             )
                 [1] => Array(
                             'name' => "Ryan",
                             'age'  => 20,
                             'marks'=> 57
                             )
                )
   [23] => Array(
                 [0] => Array(
                             'name' => "Allen",
                             'age'  => 23,
                             'marks'=> 70
                             )
                 [1] => Array(
                             'name' => "Duke",
                             'age'  => 23,
                             'marks'=> 67
                             )
                )
   [24] => Array(
                 [0] => Array(
                             'name' => "Matt",
                             'age'  => 24,
                             'marks'=> 85
                             )
                )

 )

对于特定的年龄，我只能获得一个内容。

如果我正确理解了您的问题，您可以使用此功能（使用CakePHP 3测试）获得几乎您想要的内容：

然后，您可以使用

array\u映射

和

array\u值

精确地获取所需内容：

array_map('array_values', Hash::combine($array, '{n}.name', '{n}', '{n}.age'))

不要忘记添加以下

use

语句：

use\Cake\Utility\Hash

编辑：看起来您使用的是CakePHP 2，上面的操作应该可以，您只需将
散列
替换为
集
：

array_map('array_values', Set::combine($array, '{n}.name', '{n}', '{n}.age'))

例如：

$array = array(
    0 => array(
        'name' => "Bob",
        'age'  => 20,
        'marks'=> 50
    ),
    1 => array(
        'name' => "Ryan",
        'age'  => 20,
        'marks'=> 57
    ),
    2 => array(
        'name' => "Allen",
        'age'  => 23,
        'marks'=> 70
    ),
    3 => array(
        'name' => "Duke",
        'age'  => 23,
        'marks'=> 67
    ),
    4 => array(
        'name' => "Matt",
        'age'  => 24,
        'marks'=> 85
    )
) ;
debug($array);
debug(\Cake\Utility\Hash::combine($array, '{n}.user', '{n}', '{n}.age'));
debug(array_map('array_values', \Cake\Utility\Hash::combine($array, '{n}.name', '{n}', '{n}.age')));

输出：
