将XML数组解析为php变量

Question

我有一个在一个站点上自动生成的XML提要，我试图将其复制到另一个站点并将数据导入到mysql数据库中，但是，我有困难，因为我＆＃39 ;我不熟悉分解成多个元素的数组。

它是否以与标准数组相同的方式处理，或者每个必须单独处理？输出的XML示例包含在下面;

[str] => Array
    (
        [0] => 0
        [1] => USD
        [2] => USPS
        [3] => 4228547
        [4] => 486948677
        [5] => 7
        [6] => IndyGen3
        [7] => 1
        [8] => 8 units|8
        [9] => N/A
        [10] => 1
        [11] => Unlimited Refill
        [12] => Unlimited Refill

        [1] => 8
        [2] => 1

Answer 1

要访问多维数组中的信息（如上所示），请使用以下表示法。假设您的主阵列名为$arr。

$sql = "INSERT INTO `mytable`
(
    `currency`,
    `postal_service`,
    `date`,
    `amount_1`,
    `amount_2`
) VALUES (
    '".$arr[str][1]."',
    '".$arr[str][2]."',
    '".$arr[date][0]."',
    '".$arr[float][0]."',
    '".$arr[float][1]."'
)";

这相当于：

$sql = "INSERT INTO `mytable`
(
    `currency`,
    `postal_service`,
    `date`,
    `amount_1`,
    `amount_2`
) VALUES (
    'USD',
    'USPS',
    '2013-02-15T19:35:15.438Z',
    '94.88',
    '94.88'
)";
