有没有一种简单的方法可以将PHP关联数组封送到XML和从XML封送？例如，我有以下数组：
$items = array("1", "2",
array(
"item3.1" => "3.1",
"item3.2" => "3.2"
"isawesome" => true
)
);
如何将其尽可能少地转换为类似于以下XML的内容，然后再返回？
<items>
<item>1</item>
<item>2</item>
<item>
<item3_1>3.1</item3_1>
<item3_2>3.2</item3_2>
<isawesome>true</isawesome>
</item>
</items>
我真的不在乎是否需要更改数组结构或者出现的XML与上面的示例不同。我一直在尝试使用PHP的XMLReader和XMLWriter，但是文档很差，而我生成的代码看起来就像我认为的那样：
$xml = SomeXMLWriter::writeArrayToXml($items);
$array = SomeXMLWriter::writeXmlToArray($xml);
在不编写我自己的自定义类的情况下获取PHP数组的基本原始XML转储是否真的必须更难？
我尽量避免使用PEAR。除了我曾经遇到的配置问题之外，我从来没有坚持过任何我用过的软件包。

SimpleXML非常适合您的使用。
答案 1 :(得分：6)
对于那些没有使用PEAR包的人，但是你已经安装了PHP5。这对我有用：
/**

*
* @param array $data Associative Array containing values to be parsed into an XML Data Set(s)
* @param string $startElement Root Opening Tag, default fx_request
* @param string $xml_version XML Version, default 1.0
* @param string $xml_encoding XML Encoding, default UTF-8
* @return string XML String containig values
* @return mixed Boolean false on failure, string XML result on success
*/
public function buildXMLData($data, $startElement = 'fx_request', $xml_version = '1.0', $xml_encoding = 'UTF-8') {
if(!is_array($data)) {
$err = 'Invalid variable type supplied, expected array not found on line '.__LINE__." in Class: ".__CLASS__." Method: ".__METHOD__;
trigger_error($err);
if($this->_debug) echo $err;
return false; //return false error occurred
}
$xml = new XmlWriter();
$xml->openMemory();
$xml->startDocument($xml_version, $xml_encoding);
$xml->startElement($startElement);
/**
* Write XML as per Associative Array
* @param object $xml XMLWriter Object
* @param array $data Associative Data Array
*/
function write(XMLWriter $xml, $data) {
foreach($data as $key => $value) {
if(is_array($value)) {
$xml->startElement($key);
write($xml, $value);
$xml->endElement();
continue;
}
$xml->writeElement($key, $value);
}
}
write($xml, $data);
$xml->endElement();//write end element
//Return the XML results
return $xml->outputMemory(true);
}
答案 2 :(得分：3)
我遇到了一些相同的问题，所以我创建了两个类：
<强> BXML
扩展SimpleXml并纠正其中一些问题的类。就像无法添加CData节点或Comment节点一样。我还添加了一些额外的功能，比如使用php流功能添加子节点$oXml->AddChild("file:///user/data.xml")或添加像$oXml->AddChild("<more><xml>yes</xml></more>");这样的XML字符串子节点，但基本上我只是想修复simpleXML问题。
<强> bArray
我扩展了ArrayObject类，以便所有数组功能都可以面向对象并保持一致，因此您不需要记住array_walk通过引用对数组进行操作，而array_filter则按值对数组进行操作。因此，您可以执行$oArray->flip()->Reverse()->Walk(/*callback*/);之类的操作，然后仍然可以按照通常的方式$oArray[key]访问该值。
这两种方法都将自己输出为Arrays和Xml，因此您可以在它们之间无缝跳转。所以你可以$oXml->AsArray();或$oArray->AsXml();我发现这样做比在array2xml或xml2array方法之间不断传递事物更容易。
http://code.google.com/p/blibrary/source
可以覆盖这两个类以创建您选择的自定义类，并且可以彼此独立使用。

is_array($v)

}
return ($first === NULL) ? $xml->asXML() : $xml;
}
public static function to_array($xml)
{
$xml = simplexml_load_string($xml);
$json = json_encode($xml);
return json_decode($json,TRUE);
}
}
$xml = xml::from_array($array);
$array = xml::to_array($xml);

你见过PEAR包XML_Serializer吗？
答案 5 :(得分：2)
一般尝试Zend_Config和Zend Framework。
我想这将是一个两步过程：数组到Zend_Config，Zend_Config到XML。
答案 6 :(得分：2)
听起来像SimpleXML的工作。
我建议稍微不同的XML结构..
并且想知道为什么你需要从数组转换 - ＆gt; XML和返回..如果你可以像你说的那样修改数组结构，为什么不只是生成XML呢？如果某些代码已经存在并采用该数组配置，则只需修改它以接受XML。那么你有1种数据格式/输入类型，根本不需要转换..
<items>
<item id="1"/>
<item id="2"/>
<item id="3">
<subitems>
<item id="3.1"/>
<item id="3.2" isawesome="true"/>
</subitems>
</item>
</items>
答案 7 :(得分：2)
这是我编写的一个函数，用于获取XML并将其转换为PHP关联数组。一个警告是id当前不处理属性或c数据。虽然它会通过将重复的XML标记放置在以标记命名的数组中来处理重复的XML标记。

嘿@Conrad我只是修改你的代码以适应数字数组：

* @return string XML String containig values
* @return mixed Boolean false on failure, string XML result on success
*/
public static function arrayToXML($data, $startElement = 'fx_request', $xml_version = '1.0', $xml_encoding = 'UTF-8'){
if(!is_array($data)){
$err = 'Invalid variable type supplied, expected array not found on line '.__LINE__." in Class: ".__CLASS__." Method: ".__METHOD__;
trigger_error($err);
if($this->_debug) echo $err;
return false; //return false error occurred
}
$xml = new XmlWriter();
$xml->openMemory();

我同意这是PHP文档丢弃的一个方面，但对我来说，我总是使用SimpleXML与xml2Array函数混合使用。在print_r之类的转储函数的帮助下，从simpleXML获得的Xml并不难以导航。

之后只需使用ArrayToXML类。例如：
$xml = new ArrayToXML();
print $xml->buildXML($input);

下面的类使用simplexml来实现相同的功能，你只需要遍历数组并调用ximplexml的addchild。

从xml字符串获取assoc数组的最简单方法：
<?
$data_array = (array) simplexml_load_string($xml_string);
?>
