filtering with 2 dimensions

$attributeMap = [
    'name' => 'Mr. Bean',
    'phone' => '12345' ,
    'pets' => [
        [
            'name'=>'goofy',
            'family'=>'dog'
        ],
        [
            'name'=>'twitty',
            'family'=>'dinosaur'
        ]
    ]
];

$filter = ['name','phone','pets' => ['name']];

// i wanted to use the $filter to make attributeMap look like this:
// ['name'=>'Mr. Bean', 'phone' => '12345', 'address'=>['city'=>'hogs']]

// what i was only able to do is to create a 1 dimensional filter
