我创建一个数组，然后将 0..n 个元素压入数组中的子数组之一 (最容易明白我在下面的代码中的意思)

当我通过 XML_Serializer 运行数组时，它会在推送的元素周围添加额外的标签

$serializer_options = array(
    XML_SERIALIZER_OPTION_INDENT => '    ',
    XML_SERIALIZER_OPTION_RETURN_RESULT => TRUE,
    rootName => 'JZ_2103'
);
$serializer = &new XML_Serializer($serializer_options);

$otXmlArr = array(
    'status' => 'success',
    'reason' => 'null',
    'payload' => array(
        'ContactsResponse' => array()
    )
);

foreach ($mydata as $item) {
    array_push($otXmlArr['payload']['ContactsResponse'],
        array(
            'Contact' => array(
                'ID' => $item['id'],
                'FirstName' => $item['fname']
            )
        )
    );
}

$otXml = $serializer->serialize($otXmlArr);

创建的 xml 有额外的标签 <XML_Serializer_Tag> .如何消除这些标签？

<JZ_2103>
    <status>success</status>
    <reason>null</reason>
    <payload>
        <ContactsResponse>
            <XML_Serializer_Tag>
                <Contact>
                    <ID>10</ID>
                    <FirstName>Roy</FirstName>
                </Contact>
            </XML_Serializer_Tag>
        </ContactsResponse>
    </payload>
</JZ_2103>

Abstr 的解决方案几乎可行 - 它产生:

来自数组的print_r:

Array
(
    [status] => success
    [reason] => null
    [payload] => Array
        (
            [ContactsResponse] => Array
                (
                    [0] => Array
                        (
                            [Contact] => Array
                                (
                                    [ID] => 3
                                    [FirstName] => Joe
                                )

                        )

                    [1] => Array
                        (
                            [Contact] => Array
                                (
                                    [ID] => 4
                                    [FirstName] => Fred
                                )

                        )

                )

        )

)

序列化 XML:

<JZ_2103>
    <status>success</status>
    <reason>null</reason>
    <payload>
        <ContactsResponse>
            <Contact>
                <ID>3</ID>
                <FirstName>Joe</FirstName>
            </Contact>
        </ContactsResponse>
        <ContactsResponse>
            <Contact>
                <ID>4</ID>
                <FirstName>Fred</FirstName>
            </Contact>
        </ContactsResponse>
    </payload>
</JZ_2103>

根据 Daniel 的建议，XML 输出为: 额外的嵌套级别:-(

<JZ_2103>
    <status>success</status>
    <reason>null</reason>
    <payload>
        <ContactsResponse>
            <Contact>
                <Contact>
                    <ID>3</ID>
                    <FirstName>Joe</FirstName>
                </Contact>
            </Contact>
            <Contact>
                <Contact>
                    <ID>4</ID>
                    <FirstName>Fred</FirstName>
                </Contact>
            </Contact>
        </ContactsResponse>
    </payload>
</JZ_2103>

我打算放弃使用序列化程序，而直接使用我认为的 simpleXml 构建 xml。这一切都是为了节省时间而开始的，很明显，它没有!

感谢 Daniel 和 Abstr 的帮助，即使这并没有让我到达终点。

最佳答案

将 'mode' => 'simplexml' 添加到 $serializer_options 应该:

$serializer_options = array(
    XML_SERIALIZER_OPTION_INDENT => '    ',
    XML_SERIALIZER_OPTION_RETURN_RESULT => TRUE,
    'rootName' => 'JZ_2103',
    'mode' => 'simplexml', 
);

或者使用常量，

$serializer_options = array(
    XML_SERIALIZER_OPTION_INDENT => '    ',
    XML_SERIALIZER_OPTION_RETURN_RESULT => TRUE,
    XML_SERIALIZER_OPTION_ROOT_NAME => 'JZ_2103',
    XML_SERIALIZER_OPTION_MODE => XML_SERIALIZER_MODE_SIMPLEXML,
);

找到了 here在第 515 行。

// use XML_SERIALIZER_MODE_SIMPLEXML to use parent name as tagname

// if transforming an indexed array

XML_SERIALIZER_OPTION_MODE => XML_SERIALIZER_MODE_DEFAULT,

编辑:更新为指向实际的 XML_Serializer 代码库。

应该对代码进行如下更改(感谢@danielpsc，请参阅评论):

$otXmlArr = array(
    'status' => 'success',
    'reason' => 'null',
    'payload' => array(
        'ContactsResponse' => array(
            'Contact' => array()
        )
    )
);

foreach ($mydata as $item) {
    array_push($otXmlArr['payload']['ContactsResponse']['Contact'],
        array(
            'ID' => $item['id'],
            'FirstName' => $item['fname']
        )
    );
}
