如何在Laravel中将数组和子数组转换为集合？

Question

我想将所有静态数据转换为 Laravel 中的集合。

这是我的数据：

static $menu_list = [
    [
        'path' => 'admin/report/transaction',
        'active' => 'admin/report',
        'name' => 'Report',
        'icon' => 'file-text',
        'children' => [
            'path' => 'admin/report/transaction',
            'active' => 'admin/report/transaction',
            'name' => 'Transaction',
        ],
    ],
];

此函数将我的数据转换为数组：

public static function menuList()
{
    $menu_list = collect(self::$menu_list)->map(function ($voucher) {
        return (object) $voucher;
    });
}

但是上面的函数只能转换main of array，不能将children => [...]转换为collection

Answer 1

您需要在 map() 中再次使用 collect():

public static function menuList()
{
    $menu_list = collect(self::$menu_list)->map(function ($voucher) {
        return (object) array_merge($voucher, [
            'children' => collect($voucher['children'])
        ]);
    });
}

Answer 2

你需要一个递归调用。

public static function convertToCollection()
{
    $menu_list = self::menuList(self::$menu_list);
}

public static function menuList($list)
{
    return collect($list)->map(function ($voucher) {
        if(is_array($voucher)) {
          return self::menuList($voucher)
        }
        return $voucher;
    });
}

Answer 3

只需在您的方法中添加一个小的代码和平。

  $menu_list = collect(self::$menu_list)->map(function ($voucher) {
             $voucher['children'] = (object) $voucher['children'];
            return (object) $voucher;
        });

输出

   Illuminate\Support\Collection {#574 ▼
  #items: array:1 [▼
    0 => {#573 ▼
      +"path": "admin/report/transaction"
      +"active": "admin/report"
      +"name": "Report"
      +"icon": "file-text"
      +"children": {#567 ▼
        +"path": "admin/report/transaction"
        +"active": "admin/report/transaction"
        +"name": "Transaction"
      }
    }
  ]
}
