从关联数组获取值

Question

嗨，我有一个如下数组。我想获取每个数组的名称并像这样存储它$Obj>names[] = *****; $ obj变量是这样定义的$Obj = (object)Null;

array (
  0 => 
  array (
    'name' => 'dean',
    'id' => 538,
  ),
  1 => 
  array (
    'name' => 'zia',
    'id' => 53,
  ),
  2 => 
  array (
    'name' => 'naida',
    'id' => 5,
  ),
  3 => 
  array (
    'name' => 'lola',
    'id' => 78,
  ),
)  

结果应该像这样（控制台）data: {names: Array(4)}

names: Array(4)
0: "dean"
1: "zia"
2:"naida"
3:"lola"

Answer 1

您可以使用Laravel的辅助函数Arr::pluck：

Arr::pluck

您还可以传递第三个参数来获取键控结果：

use Illuminate\Support\Arr;

$array = [
    // Your array
    //...
];

$names = Arr::pluck($array, 'name');

// ['dean', 'zia', 'naida', 'lola']

Answer 2

$names = Arr::pluck($array, 'name', 'id');

// [538 => 'dean', 53 => 'zia', 5 => 'naida', 78 => 'lola']

OR

$names = [];
foreach($myArray as $element ){
$names[] = $element['name'];
}
