这个PHP数组怎么处理？请教！

Question

原数组

$arr = [
            [
                'name'  => '国家站',
                'title' => '美国站',
                'pic'   => '111'
            ],
            [
                'name'  => '国家站',
                'title' => '英国站',
                'pic'   => '222'

            ],
            [
                'name'  => '排行榜',
                'title' => '每日',
                'pic'   => '333'

            ],
            [
                'name'  => '排行榜',
                'title' => '每月',
                'pic'   => '444'

            ]
        ];

转换成

$arr1=[
            [
                'name'=>'国家站',
                'list'=>[
                    [
                        'title' => '美国站',
                        'pic'   => '111'
                    ],
                    [
                        'title' => '英国站',
                        'pic'   => '222'
                    ]
                ],
            ],
            [
                'name'=>'排行榜',
                'list'=>[
                    [
                        'title' => '每日',
                        'pic'   => '333'
                    ],
                    [
                        'title' => '每月',
                        'pic'   => '444'
                    ]
                ],
            ]

        ];

就是name 一样的 list合并
