我如何比較和合並兩個數組

Question

我有以下兩個來自同一數據庫的數組，它們使用相同的查詢來獲取兩個數組。 兩者都包含有關具有兩個不同行項目（物料清單）的單個銷售訂單的信息，第一個包含行項目ItemID= 600271 ，第二個包含LineItem ItemID=600274但是正如您在下面看到的，它們都具有相同的銷售訂單號[CustomerSONo] => [7] => **15020**

因此，我如何比較或合並這兩個數組。 ？

//查詢

    $result= --select statement--;
    while($row = mysqli_fetch_array($result)) {
        print_r($row);
     }

Answer 1

選項1

$orders = array();

while($row = mysqli_fetch_array($result)) {
    $orders[$row['CustomerSONo'][] = $row;
}

這會將共享同一CustomerSONo的所有行一起添加到一個數組中。 如果您有多個訂單，則可以使用來獲取所有單獨的訂單

foreach($orders as $orderNo => $order) {
    foreach($order as $key => $orderRow) {

    }
}

選項2

但是，如果您只想從每個訂單中提取ItemID，則可以執行以下操作：

$orderItems = array();
while($row = mysqli_fetch_array($result)) {
    $orderItems[$row['CustomerSONo']][] = $row['ItemID'];
}

這將創建一個名為$orderItems的數組，該數組僅將訂單號存儲在該數組中，而不是有關該訂單的所有信息。

選項3

如果要回顯這些行，則首先必須像選項2一樣對它們進行“排序”。一旦獲得了所有屬於一個CustomerSONo ItemID ，就可以執行另一個foreach循環以將它們回顯為一行。

foreach($orders as $orderNo => $itemIds) {
    echo "Order #" . $orderNo . ": " . implode(", ", $itemIds);
}

這將創建以下內容：

Order #1: 18340, 1837, 13 Order #2: 183, 868, 285, 860
