从查询结果中添加键值对，php

Question

我在下面遇到了一些问题，想将查询结果“id”添加为值“concat”的键——我需要一个 foreach 吗？最好的方法是什么？

$concatCol = mysqli_query( $connS, "SELECT id, ShipmentNumber, InvoiceNumber, BillofLading from testTable");

$data =array();
while ($row = mysqli_fetch_array($concatCol)) {
    $id = $row["id"];
    $ShipmentNumber = $row["ShipmentNumber"];
    $InvoiceNumber = $row["InvoiceNumber"];
    $BillofLading = $row["BillofLading"];

    $concat = $ShipmentNumber.$InvoiceNumber.$BillofLading;

    echo $concat."<br>";

    $data[] = $concat;

}

Answer 1

我不太确定您的预期输出是什么。但我认为以下其中一项对您有用：

$data[]['id'] = $concat;

这将产生一个这样的数组：

Array
(
  [0] => Array
  (
    [id] => ShipmentNumberInvoiceNumberBillofLanding
  )
  [1] => Array
  (
    [id] => ShipmentNumberInvoiceNumberBillofLanding
  )
)

第二个选项是：

$data[$id] = $concat;

这将产生如下结果：

Array
(
  [1] => ShipmentNumberInvoiceNumberBillofLanding
  [4] => ShipmentNumberInvoiceNumberBillofLanding
)

其中键 1 和 4 是每个返回行的 $id。在这两个示例中，ShipmentNumberInvoiceNumberBillofLanding 当然是每一行的连接值。
