如何在主数组中创建子数组

Question

我在sql数据库中有两个表，第一个是预订，它有客户详细信息，另一个是booking_line，它已经由客户购买了产品历史记录，现在我希望这两个结果都在一个数组中，如下图所示 我只想要一个名为 Customer 的数组，其中包含客户明智的所有购买详细信息

array(
        [0] => array(
                 [id] => 67
                 [name] => Neha
                 [mobile_no] => xxxxxxxxx
                 [gender] => Female
                 [Sale] => Array
                    (
                        [id] => 1
                        [booking_id] => 67
                        [barcode] => 1368
                        [product_name] => Custom Print Mattel Rakhi BE
                        [p_price] => 35
                        [price] => 100
                   )
                [Sale] => Array
                    (
                        [id] => 2
                        [booking_id] => 67
                        [barcode] => 1368
                        [product_name] => Custom Print Mattel Rakhi BE
                        [p_price] => 35
                        [price] => 100
                   )
         )
       [1] => array(
                     [id] => 68
                     [name] => Nehaxx
                     [mobile_no] => xxxxxxxxx
                     [gender] => Female
             )

目前我得到这样的输出

    array(
        [0] => array(
                 [id] => 67
                 [name] => Neha
                 [mobile_no] => xxxxxxxxx
                 [gender] => Female
         )
        [1] => array(
           [Sale] => Array
                (
                    [id] => 1
                    [booking_id] => 67
                    [barcode] => 1368
                    [product_name] => Custom Print Mattel Rakhi BE
                    [p_price] => 35
                    [price] => 100
               )
         )
        [2] => array(
                 [id] => 68
                 [name] => Nehaxx
                 [mobile_no] => xxxxxxxxx
                 [gender] => Female
         )
         [1] => array(
           [Sale] => Array
                (
                    [id] => 1
                    [booking_id] => 67
                    [barcode] => 1368
                    [product_name] => Custom Print Mattel Rakhi BE
                    [p_price] => 35
                    [price] => 100
               )
         )
)

我的代码是

$sqlA = "SELECT * FROM booking";
$resultA = $conn->query($sqlA);
$dataA = array();

while($rowA = $resultA->fetch_assoc()) {
    $sql = "SELECT * FROM booking_line WHERE booking_id=".$rowA["id"]."";
    $result = $conn->query($sql);
    $dataA[] = $rowA;
    
    while($row = $result->fetch_assoc()) {   
        $dataA[] = array("Sale" => $row);
    }
}
print_r($dataA);

问题是您将第二行数据添加到数组的顶层，而不是作为主行下方的项目。

这应该有帮助：

while($rowA = $resultA->fetch_assoc()) {
    $sql = "SELECT * FROM booking_line WHERE booking_id=".$rowA["id"]."";
    $result = $conn->query($sql);
    
    while($row = $result->fetch_assoc()) {   
        $rowA["Sale"] = $row;
    }

    $dataA[] = $rowA;
}
