Question

我试图获得两个集合的联合而不覆盖任何值：

第一集：

Collection {#246 ▼
  #items: array [▼
    0 => array [▼
      "status" => "Invoice"
      "letterPaymentAmount" => 4240.0
      "BankAccountNo" => "SEK"
      "Date" => "2017-07-15T16:32:22"
      "DueDate" => "2017-07-28T00:00:00"
      "ocr" => "3000000202"
      "lastDatePayDay" => "28"
   ]]}

第二次收集

Collection {#246 ▼
  #items: array [▼
    0 => array [▼
  "status": "Reminder",
  "letterPaymentAmount": 4300,
  "BankAccountNo": "SEK",
  "Date": "2017-08-15T16:01:30",
  "DueDate": "2017-08-30T00:00:00",
  "ocr": "3000002406",
  "lastDatePayDay": "30",
  "lastDatePayMonth": "Aug",
  "Country": "Singapore",
  "Customer": "TickTack"  
   ]]}

我想要完成这个：

Collection {#246 ▼
  #items: array [▼
    0 => array [▼
      "status" => "Invoice"
      "letterPaymentAmount" => 4240.0
      "BankAccountNo" => "SEK"
      "Date" => "2017-07-15T16:32:22"
      "DueDate" => "2017-07-28T00:00:00"
      "ocr" => "3000000202"
      "lastDatePayDay" => "28"],
    1=> [     
      "status": "Reminder",
      "letterPaymentAmount": 4300,
      "BankAccountNo": "SEK",
      "Date": "2017-08-15T16:01:30",
      "DueDate": "2017-08-30T00:00:00",
      "ocr": "3000002406",
      "lastDatePayDay": "30",
      "lastDatePayMonth": "Aug",
      "Country": "Singapore",
      "Customer": "TickTack"  ]]}

我不想覆盖任何现有的键或值，只需将它们添加到一起即可。

我尝试了union()但是它会覆盖现有的密钥，并且不会获取第一个集合中不存在的密钥。

非常感谢任何帮助

Answer 1

使用merge()

$first = collect(['One','Two']);

$second = collect(['Two','Five']);

$merged = $first->merge($second);

// $merged->all();

Answer 2

使用push在不编辑项目的情况下将新项目添加到现有馆藏。

$collection = collect([['a' => 'b']]);
$collection2 = collect([['c' => 'd']]);
$collection2->each(function ($e) use (&$collection) {
    $collection->push($e);
});

Answer 3

您使用过concat()吗？一个例子如下：

    $col1 = collect([
        ['abc' => 1, 'dec' => 2],
        ['abc' => 1, 'dec' => 6]
    ]);
    $col2 = collect([
        ['abc' => 3, 'dec' => 4, 'acd' => 2],
        ['abc' => 1, 'dec' => 8, 'acd' => 6],
    ]);

    return $col1->concat($col2);

注意：如果您在没有嵌套数组的集合上使用它，那么您可能会得到与此不同的结果。
