我试图找到一种方法来返回数组的父键的值.

例如,从下面的数组我想找出父元素的键,其中$ array ['id'] =="0002".父键是显而易见的,因为它在这里定义(它将是'产品'),但通常它是动态的,因此问题.但是'id'的'id'和值是已知的.

    [0] => Array
        (
            [data] => 
            [id] => 0000
            [name] => Swirl
            [categories] => Array
                (
                    [0] => Array
                        (
                            [id] => 0001
                            [name] => Whirl
                            [products] => Array 
                               (
                                    [0] => Array
                                        (
                                            [id] => 0002
                                            [filename] => 1.jpg
                                         )
                                    [1] => Array
                                        (
                                            [id] => 0003
                                            [filename] => 2.jpg
                                         )
                                )
                         )
                 )
          )
