How can i compare and merge two array

I have following two arrays which comes from the same database use the same query to get both. both contains information about a single sales order having two different line items(Bill of materials) the first one has Line ItemItemID= 600271 and the second one has LineItem ItemID=600274 but as you can see below they both have the same Sales Order Number [CustomerSONo] => [7] => **15020**

so How can i compare or union these two array's. ?

//query

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

Array 1

     Array ( 
           [0] => XXX001 
           [CustomerId] => XXX001

           [Customer_Bill_Name] => XXX Company Name.* 
           [2] => DHE

Option 1

$orders = array();

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

This will add all rows that share the same CustomerSONo together in one array. If you have multiple orders, you can get all the seperate orders using

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

    }
}

Option 2

If you however only want to extract the ItemIDs from each order, you can do the following:

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

This will create an array called $orderItems that only stores the order numbers in the array, rather than all the information about the order.

Option 3

If you want to echo the lines, you first have to "sort" them like in Option 2. Once you have gained all ItemIDs that belong to one CustomerSONo, you do another foreach loop to echo them into a single line.

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

This will create the following:

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