從查詢結果中添加鍵值對，php

Question

我遇到了一些問題，希望將查詢結果「id」添加爲值「concat」的鍵 - 我需要一個foreach嗎？什麼是最好的方法？

$concatCol = mysqli_query($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

我不太確定你的預期輸出是什麼。但是，我認爲有以下的人會爲你工作：

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

這將導致一個這樣的數組：

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

第二個選擇是：

$data[$id] = $concat; 

哪樣產生如下結果：

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

其中密鑰1和4是每個返回行的$id。在這兩個例子中，ShipmentNumberInvoiceNumberBillofLanding當然都是每一行的連接值。
