你可以使用胡子模板引擎，并制作一个模板，如:

{{#RECEIVER}}
<RECEIVER>
    <COMPANY>{{{COMPANY}}}</COMPANY>
    <CONTACT>{{{CONTACT}}}</CONTACT>
    <ADDRESS>{{{ADDRESS}}}</ADDRESS>
    <ZIP>{{ZIP}}</ZIP>
    <CITY>{{{CITY}}}</CITY>
</RECEIVER>
{{/RECEIVER}}
{{#DOC}}
<DOC>
    <TEXT>{{{TEXT}}}</TEXT>
    <NUMBER>{{{NUMBER}}}</NUMBER>
</DOC>
{{/DOC}}

在PHP中这样使用它:

require_once( __DIR__ .'/../controls/Mustache/Autoloader.php' );
Mustache_Autoloader::register();
$oMustache = new Mustache_Engine();
$sTemplate = implode( '', file( __DIR__ ."/xml.tpl" ));
$return = $oMustache->render($sTemplate, $res);
echo($return);

如果数组是关联的并且键是正确的，那么首先将它转换为xml可能会更容易。喜欢的东西:

  function array2xml ($array_item) {
    $xml = '';
    foreach($array_item as $element => $value)
    {
        if (is_array($value))
        {
            $xml .= "<$element>".array2xml($value)."</$element>";
        }
        elseif($value == '')
        {
            $xml .= "<$element />";
        }
        else
        {
            $xml .= "<$element>".htmlentities($value)."</$element>";
        }
    }
    return $xml;
}

$simple_xml = simplexml_load_string(array2xml($assoc_array));

另一种方法是首先创建基本的xml，例如

$simple_xml = simplexml_load_string("<array></array>");

然后对于数组的每个部分，使用类似于我的文本创建循环的东西，而不是使用simplexml函数“addChild”用于数组的每个节点。

稍后我将尝试使用这两个版本来更新这篇文章。

一个简短的例子:

<?php

$test_array = array (
  'bla' => 'blub',
  'foo' => 'bar',
  'another_array' => array (
    'stack' => 'overflow',
  ),
);
$xml = new SimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML();

结果

<?xml version="1.0"?>
<root>
  <blub>bla</blub>
  <bar>foo</bar>
  <overflow>stack</overflow>
</root>

键和值会被交换——你可以在array_walk之前用array_flip()来修复这个问题。array_walk_recursive需要PHP 5。你可以用array_walk代替，但你不会得到'stack' => 'overflow'在XML中。

如果你使用magento，你有这种类型的关联数组

$test_array = array (
    '0' => array (
            'category_id' => '582',
            'name' => 'Surat',
            'parent_id' => '565',
            'child_id' => '567',
            'active' => '1',
            'level' => '6',
            'position' => '17'
    ),

    '1' => array (
            'category_id' => '567', 
            'name' => 'test',
            'parent_id' => '0',
            'child_id' => '576',
            'active' => '0',
            'level' => '0',
            'position' => '18'
    ),
);

那么最好将关联数组转换为XML格式。在控制器文件中使用此代码。

$this->loadLayout(false);
//header ("content-type: text/xml");
$this->getResponse()->setHeader('Content-Type','text/xml');
$this->renderLayout();

$clArr2xml = new arr2xml($test_array, 'utf-8', 'listdata');
$output = $clArr2xml->get_xml();
print $output; 

class arr2xml
{
var $array = array();
var $xml = '';
var $root_name = '';
var $charset = '';

public function __construct($array, $charset = 'utf-8', $root_name = 'root')
{
    header ("content-type: text/xml");
    $this->array = $array;
    $this->root_name = $root_name;
    $this->charset = $charset;

    if (is_array($array) && count($array) > 0) {
        $this->struct_xml($array);

    } else {
        $this->xml .= "no data";
    }
}

public function struct_xml($array)
{
    foreach ($array as $k => $v) {
        if (is_array($v)) {
            $tag = ereg_replace('^[0-9]{1,}', 'item', $k); // replace numeric key in array to 'data'
            $this->xml .= "<$tag>";
            $this->struct_xml($v);
            $this->xml .= "</$tag>";
        } else {
            $tag = ereg_replace('^[0-9]{1,}', 'item', $k); // replace numeric key in array to 'data'
            $this->xml .= "<$tag><![CDATA[$v]]></$tag>";
        }
    }
}

public function get_xml()
{

    $header = "<?xml version=\"1.0\" encoding=\"" . $this->charset . "\"?><" . $this->root_name . ">";
    $footer = "</" . $this->root_name . ">";

    return $header . $this->xml . $footer;
}
}

我希望这对大家都有帮助。

function array2xml($array, $xml = false){

    if($xml === false){

        $xml = new SimpleXMLElement('<?xml version=\'1.0\' encoding=\'utf-8\'?><'.key($array).'/>');
        $array = $array[key($array)];

    }
    foreach($array as $key => $value){
        if(is_array($value)){
            $this->array2xml($value, $xml->addChild($key));
        }else{
            $xml->addChild($key, $value);
        }
    }
    return $xml->asXML();
}
