Laravel获取数字？

Question

如何在Laravel中获取数组数组？

---

下面是我得到了什么：

$companies = Company::select(['id','name'])->get()->toArray(); 

这让我回：

array:21 [ 
    0 => array:2 [ 
     "id" => 21 
     "name" => "Cool Company" 
    ] 
    1 => array:2 [ 
     "id" => 4 
     "name" => "Bacon Co" 
    ] 
    .... 

但我想：

array:21 [ 
    0 => array:2 [ 
     21, 
     "Cool Company" 
    ] 
    1 => array:2 [ 
     4, 
     "Bacon Co" 
    ] 
    ....

如果你需要这个精确的输出你可以做

$companies = App\Company::pluck('name', 'id') 
    ->map(function ($name, $id) { 
     return [$id, $name]; 
    }) 
    ->values() 
    ->toArray(); 

输出：

 
=> [ 
    [ 
     4, 
     "Bacon Co", 
    ], 
    [ 
     21, 
     "Cool Company", 
    ], 
    ]

不知道你正在使用它，但后来也许做的pluck()只是输出就足够了

$companies = App\Company::pluck('name', 'id')->toArray(); 

 
=> [ 
    4 => "Bacon Co", 
    21 => "Cool Company", 
    ]
