XML 到 PHP 数组？答案

【问题标题】：XML to PHP Array?XML 到 PHP 数组？

【问题描述】：

我正在尝试编辑开源 PHP 包装器以导出 XML。

原文：

$new_invoice = array(
    array(
        "Type"=>"ACCREC",
        "Contact" => array(
            "ContactID" => "[contact id]"
        ),
        "Date" => "2010-04-08",
        "DueDate" => "2010-04-30",
        "Status" => "SUBMITTED",
        "LineAmountTypes" => "Exclusive",
        "LineItems"=> array(
            "LineItem" => array(
                array(
                    "Description" => "Just another test invoice",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                )
            )
        )
    )
);

我添加了另一个 LineItem，所以它变成了这样：

$new_invoice = array(
    array(
        "Type"=>"ACCREC",
        "Contact" => array(
            "ContactID" => "7937FF1D-B135-4BD0-A219-4B621EA3808C"
        ),
        "Date" => "2010-04-08",
        "DueDate" => "2010-04-30",
        "Status" => "DRAFT",
        "LineAmountTypes" => "Exclusive",
        "LineItems"=> array(
            "LineItem" => array(
                array(
                    "Description" => "Just another test invoice",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                )
            )
            "LineItem" => array(
                array(
                    "Description" => "Just another test invoice2",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                )
            )
        )
    )
);

但我收到一条错误消息，上面写着“期待一个右括号）似乎所有的括号都在那里，所以我很困惑。

【解决方案1】：

您在第一个 LineItem 数组后遗漏了一个逗号。

此外，由于您的两个数组共享相同的键（“LineItem”），第二个将覆盖第一个，但这与语法错误无关。

编辑：处理这个问题（这里假设正在使用 SimpleXML 之类的东西）：

"LineItems"=> array(
    "LineItem" => array(
        array(
            "Description" => "Just another test invoice",
            "Quantity" => "2.0000",
            "UnitAmount" => "250.00",
            "AccountCode" => "200"
        ),
        array(
            "Description" => "Just another test invoice2",
            "Quantity" => "2.0000",
            "UnitAmount" => "250.00",
            "AccountCode" => "200"
        )
    )
)

您在第一个行项之后忘记了逗号...

您的代码应如下所示：

<?php 
$new_invoice = array(
    array(
        "Type"=>"ACCREC",
        "Contact" => array(
            "ContactID" => "7937FF1D-B135-4BD0-A219-4B621EA3808C"
        ),
        "Date" => "2010-04-08",
        "DueDate" => "2010-04-30",
        "Status" => "DRAFT",
        "LineAmountTypes" => "Exclusive",
        "LineItems"=> array(
            "0" => array(
                array(
                    "Description" => "Just another test invoice",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                )
            ),
            "1" => array(
                array(
                    "Description" => "Just another test invoice2",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                )
            )
        )
    )
);
?>

您的第二个订单项也将覆盖第一个订单项。

我会推荐一个计数器，并在添加每个 lineitem 后递增它...

这是缺少的逗号，但正如其他人所说，第二个会覆盖第一个。试试这个：

$new_invoice = array(
    array(
        "Type"=>"ACCREC",
        "Contact" => array(
            "ContactID" => "7937FF1D-B135-4BD0-A219-4B621EA3808C"
        ),
        "Date" => "2010-04-08",
        "DueDate" => "2010-04-30",
        "Status" => "DRAFT",
        "LineAmountTypes" => "Exclusive",
        "LineItems"=> array(
            "LineItem" => array(
                array(
                    "Description" => "Just another test invoice",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                ),
                array(
                    "Description" => "Just another test invoice2",
                    "Quantity" => "2.0000",
                    "UnitAmount" => "250.00",
                    "AccountCode" => "200"
                )
            )
        )
    )
);
print_r($new_invoice);

在第一个“lineitem”之后，您的数组中仅缺少逗号 (,)
