php - 在 Laravel 中搜索数组

Question

我得到了两个数组并将它们合并，然后在 name 下寻找某个值，但似乎无法让它工作

$temp = [
    ['id' => 3, 'name' => 'Taylor'],
    ['id' => 3, 'name' => 'Abigail'],
];

 $temp1 = [
     ['id' => 3, 'name' => 'Taylor'],
     ['id' => 3, 'name' => 'Taylor'],
];

$ggg = array_merge($temp,$temp1);

Answer 1

使用 contains()集合的方法。架构:

collect($array1)               // Create a collection from the first array
    ->merge($array2)           // merge it with the second array
    ->contains($key, $value);  // returns boolean

您的代码:

$temp = [
    ['id' => 3, 'name' => 'Taylor'],
    ['id' => 3, 'name' => 'Abigail'],
];

$temp1 = [
     ['id' => 3, 'name' => 'Taylor'],
     ['id' => 3, 'name' => 'Taylor'],
];

collect($temp)->merge($temp1)->contains('name', 'Taylor');  // true
collect($temp)->merge($temp1)->contains('name', 'Jane');  // false

如果要获取符合条件的项目，请使用 where() :

$result = collect($temp)->merge($temp1)->where('name', 'Taylor');

这将返回:

Collection {#465 ▼
  #items: array:3 [▼
    0 => array:2 [▼
      "id" => 3
      "name" => "Taylor"
    ]
    2 => array:2 [▼
      "id" => 3
      "name" => "Taylor"
    ]
    3 => array:2 [▼
      "id" => 3
      "name" => "Taylor"
    ]
  ]
}
