相关疑难解决方法(0)

我有一个多维数组,如下所示:

$array = (
    [0] => array (
        ['WS'] => array(
             [id] => 2,
             [name] => 'hello'
             )
        )
    ), 
    [1] => array (
        ['SS'] => array(
             [id] => 1,
             [name] => 'hello2'
             )
        )
    ),
    [2] => array (
        ['WS'] => array(
             [id] => 5,
             [name] => 'helloAGAIN'
             )
        )
)

如您所见,$ array [0]和$ array [2]具有相同的密钥[WS].我需要一个函数来找到那些"相同的键".然后我将这两个数组合并为一个.FE

$array =
(
    [0] => array 
        (
            ['WS'] => array
                (
                     [0] => array
                         (
                             [id] => 2,
                             [name] => 'hello'
                         ),
                     [1] …
