php - 如何在不覆盖任何值的情况下合并两个集合

Question

我试图在不覆盖任何值的情况下获取两个集合的并集:

第一个集合:

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，只是将它们加在一起。

我已经尝试过 union() 但它会覆盖现有的键并且不会采用第一个集合中不存在的键。

任何帮助将不胜感激

你用过concat()吗？ ？示例如下:

    $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);

Note: if you use this on a collection without nested array then you might get different result from this one.
