Question

我想将以下多维数组转换为单数组。子数组的仅 parent_id列应与父数组的category_id相同。而且，sort_order_number子数组应该等于它们在 children 数组中的位置。父数组的sort_order_number应该等于它们在 parent 数组中的位置：

当前的多维数组 ：

array:2 [▼
  0 => array:12 [▼
    "text_az" => "title1"
    "text_en" => "title1.1"
    "text_ru" => "title1.2"
    "slug" => "sfsf"
    "icon" => "fa fa-bell"
    "target" => "_top"
    "id" => 1
    "sort_order_number" => 1
    "parent_id" => null
    "created_at" => null
    "updated_at" => null
    "children" => array:1 [▼
      0 => array:12 [▼
        "text_az" => "title3"
        "text_en" => "title3.1"
        "text_ru" => "title3.2"
        "slug" => "sdf"
        "icon" => "fa fa-bell"
        "target" => "_top"
        "id" => 3
        "sort_order_number" => 1
        "parent_id" => null
        "created_at" => null
        "updated_at" => null
        "children" => array:1 [▼
          0 => array:11 [▼
            "text_az" => "title2"
            "text_en" => "title2.1"
            "text_ru" => "title2.2"
            "slug" => "fsdfsf"
            "icon" => "fa fa-bell"
            "target" => "_top"
            "id" => 2
            "sort_order_number" => 2
            "parent_id" => null
            "created_at" => null
            "updated_at" => null
          ]
        ]
      ]
    ]
  ]
  1 => array:11 [▼
    "text_az" => "title4"
    "text_en" => "title4.1"
    "text_ru" => "title4.2"
    "slug" => "treteterter"
    "icon" => "fa fa-bell"
    "target" => "_top"
    "id" => 4
    "sort_order_number" => 2
    "parent_id" => null
    "created_at" => null
    "updated_at" => null
  ]
]

转换后我想拥有的单维数组：

array:3 [▼
  0 => array:12 [▼
    "text_az" => "title1"
    "text_en" => "title1.1"
    "text_ru" => "title1.2"
    "slug" => "sfsf"
    "icon" => "fa fa-bell"
    "target" => "_top"
    "id" => 1
    "sort_order_number" => 1
    "parent_id" => null
    "created_at" => null
    "updated_at" => null
  ]
  1 => array:12 [▼
    "text_az" => "title3"
    "text_en" => "title3.1"
    "text_ru" => "title3.2"
    "slug" => "sdf"
    "icon" => "fa fa-bell"
    "target" => "_top"
    "id" => 3
    "sort_order_number" => 1
    "parent_id" => 1
    "created_at" => null
    "updated_at" => null

  ]
  2 => array:12 [▼
    "text_az" => "title2"
    "text_en" => "title2.1"
    "text_ru" => "title2.2"
    "slug" => "fsdfsf"
    "icon" => "fa fa-bell"
    "target" => "_top"
    "id" => 2
    "sort_order_number" => 2
    "parent_id" => 3
    "created_at" => null
    "updated_at" => null

  ]
  3 => array:12 [▼
    "text_az" => "title4"
    "text_en" => "title4.1"
    "text_ru" => "title4.2"
    "slug" => "treteterter"
    "icon" => "fa fa-bell"
    "target" => "_top"
    "id" => 4
    "sort_order_number" => 2
    "parent_id" => null
    "created_at" => null
    "updated_at" => null

  ]

由于数组是固定结构，您可以这样做， simple demo

$result = [];
$count = 1;
$temp = [];
array_walk_recursive($array, function($v, $k) use(&$result, &$count, &$temp) {
    $temp[$k] = $v;
    if($count++ % 11 == 0) {
        $temp["sort_order_number"] = intval($count / 11);
        $result[] = $temp;
        $temp = [];
    }
});
