这是php 5.2代码,它将任何深度的数组转换为xml文档:
Array
(
['total_stud']=> 500
[0] => Array
(
[student] => Array
(
[id] => 1
[name] => abc
[address] => Array
(
[city]=>Pune
[zip]=>411006
)
)
)
[1] => Array
(
[student] => Array
(
[id] => 2
[name] => xyz
[address] => Array
(
[city]=>Mumbai
[zip]=>400906
)
)
)
)
生成的XML将如下:
<?xml version="1.0"?>
<student_info>
<total_stud>500</total_stud>
<student>
<id>1</id>
<name>abc</name>
<address>
<city>Pune</city>
<zip>411006</zip>
</address>
</student>
<student>
<id>1</id>
<name>abc</name>
<address>
<city>Mumbai</city>
<zip>400906</zip>
</address>
</student>
</student_info>
PHP片段
<?php
// function definition to convert array to xml
function array_to_xml( $data, &$xml_data ) {
foreach( $data as $key => $value ) {
if( is_numeric($key) ){
$key = 'item'.$key; //dealing with <0/>..<n/> issues
}
if( is_array($value) ) {
$subnode = $xml_data->addChild($key);
array_to_xml($value, $subnode);
} else {
$xml_data->addChild("$key",htmlspecialchars("$value"));
}
}
}
// initializing or creating array
$data = array('total_stud' => 500);
// creating object of SimpleXMLElement
$xml_data = new SimpleXMLElement('<?xml version="1.0"?><data></data>');
// function call to convert array to xml
array_to_xml($data,$xml_data);
//saving generated xml file;
$result = $xml_data->asXML('/file/path/name.xml');
?>
SimpleXMLElement::asXML此代码段中使用的文档

一个简短的:
<?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();
结果是
<?xml version="1.0"?>
<root>
<blub>bla</blub>
<bar>foo</bar>
<overflow>stack</overflow>
</root>
键和值是交换的 - 您可以array_flip()在array_walk之前修复它.array_walk_recursive需要PHP 5.你可以使用array_walk,但你不会进入'stack' => 'overflow'xml.

这里提供的答案只将数组转换为带节点的XML,您无法设置属性.我编写了一个php函数,允许您将数组转换为php,并为xml中的特定节点设置属性.这里的缺点是你必须以一种特殊的方式构造一个数组,几乎没有约定(只有你想使用属性)
以下示例将允许您在XML中设置属性.
详细示例和用法可在此处找到:http: //www.lalit.org/lab/convert-php-array-to-xml-with-attributes/
<?php
$books = array(
'@attributes' => array(
'type' => 'fiction'
),
'book' => array(
array(
'@attributes' => array(
'author' => 'George Orwell'
),
'title' => '1984'
),
array(
'@attributes' => array(
'author' => 'Isaac Asimov'
),
'title' => 'Foundation',
'price' => '$15.61'
),
array(
'@attributes' => array(
'author' => 'Robert A Heinlein'
),
'title' => 'Stranger in a Strange Land',
'price' => array(
'@attributes' => array(
'discount' => '10%'
),
'@value' => '$18.00'
)
)
)
);
/* creates
<books type="fiction">
<book author="George Orwell">
<title>1984</title>
</book>
<book author="Isaac Asimov">
<title>Foundation</title>
<price>$15.61</price>
</book>
<book author="Robert A Heinlein">
<title>Stranger in a Strange Land</title>
<price discount="10%">$18.00</price>
</book>
</books>
*/

我找到了使用太多代码的所有答案.这是一个简单的方法:
function to_xml(SimpleXMLElement $object, array $data)
{
foreach ($data as $key => $value) {
if (is_array($value)) {
$new_object = $object->addChild($key);
to_xml($new_object, $value);
} else {
// if the key is an integer, it needs text with it to actually work.
if ($key == (int) $key) {
$key = "key_$key";
}
$object->addChild($key, $value);
}
}
}
然后将数组发送到使用递归的函数是一件简单的事情,因此它将处理一个多维数组:
$xml = new SimpleXMLElement('<rootTag/>');
to_xml($xml, $my_array);
现在$ xml包含一个漂亮的XML对象,它基于你的数组,就像你编写它一样.
print $xml->asXML();

<?php
function array_to_xml(array $arr, SimpleXMLElement $xml)
{
foreach ($arr as $k => $v) {
is_array($v)
? array_to_xml($v, $xml->addChild($k))
: $xml->addChild($k, $v);
}
return $xml;
}
$test_array = array (
'bla' => 'blub',
'foo' => 'bar',
'another_array' => array (
'stack' => 'overflow',
),
);
echo array_to_xml($test_array, new SimpleXMLElement('<root/>'))->asXML();

从PHP 5.4开始
function array2xml($data, $root = null){
$xml = new SimpleXMLElement($root ? '<' . $root . '/>' : '<root/>');
array_walk_recursive($data, function($value, $key)use($xml){
$xml->addChild($key, $value);
});
return $xml->asXML();
}

另一项改进:
/**
* Converts an array to XML
*
* @param array $array
* @param SimpleXMLElement $xml
* @param string $child_name
*
* @return SimpleXMLElement $xml
*/
public function arrayToXML($array, SimpleXMLElement $xml, $child_name)
{
foreach ($array as $k => $v) {
if(is_array($v)) {
(is_int($k)) ? $this->arrayToXML($v, $xml->addChild($child_name), $v) : $this->arrayToXML($v, $xml->addChild(strtolower($k)), $child_name);
} else {
(is_int($k)) ? $xml->addChild($child_name, $v) : $xml->addChild(strtolower($k), $v);
}
}
return $xml->asXML();
}
用法:
$this->arrayToXML($array, new SimpleXMLElement('<root/>'), 'child_name_to_replace_numeric_integers');

这是我的入门,简单而干净..
function array2xml($array, $xml = false){
if($xml === false){
$xml = new SimpleXMLElement('<root/>');
}
foreach($array as $key => $value){
if(is_array($value)){
array2xml($value, $xml->addChild($key));
}else{
$xml->addChild($key, $value);
}
}
return $xml->asXML();
}
header('Content-type: text/xml');
print array2xml($array);

所以无论如何...我拿了onokazu的代码(谢谢!)并添加了在XML中重复标记的能力,它还支持属性,希望有人发现它有用!
<?php
function array_to_xml(array $arr, SimpleXMLElement $xml) {
foreach ($arr as $k => $v) {
$attrArr = array();
$kArray = explode(' ',$k);
$tag = array_shift($kArray);
if (count($kArray) > 0) {
foreach($kArray as $attrValue) {
$attrArr[] = explode('=',$attrValue);
}
}
if (is_array($v)) {
if (is_numeric($k)) {
array_to_xml($v, $xml);
} else {
$child = $xml->addChild($tag);
if (isset($attrArr)) {
foreach($attrArr as $attrArrV) {
$child->addAttribute($attrArrV[0],$attrArrV[1]);
}
}
array_to_xml($v, $child);
}
} else {
$child = $xml->addChild($tag, $v);
if (isset($attrArr)) {
foreach($attrArr as $attrArrV) {
$child->addAttribute($attrArrV[0],$attrArrV[1]);
}
}
}
}
return $xml;
}
$test_array = array (
'bla' => 'blub',
'foo' => 'bar',
'another_array' => array (
array('stack' => 'overflow'),
array('stack' => 'overflow'),
array('stack' => 'overflow'),
),
'foo attribute1=value1 attribute2=value2' => 'bar',
);
$xml = array_to_xml($test_array, new SimpleXMLElement('<root/>'))->asXML();
echo "$xml\n";
$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML($xml);
$dom->formatOutput = TRUE;
echo $dom->saveXml();
?>

我想要一个代码，它将获取数组中的所有元素并将它们视为属性，并将所有数组视为子元素。
所以对于像
array (
'row1' => array ('head_element' =>array("prop1"=>"some value","prop2"=>array("empty"))),
"row2"=> array ("stack"=>"overflow","overflow"=>"overflow")
);
我会得到这样的东西
<?xml version="1.0" encoding="utf-8"?>
<someRoot>
<row1>
<head_element prop1="some value">
<prop2 0="empty"/>
</head_element>
</row1>
<row2 stack="overflow" overflow="stack"/>
</someRoot>
为了实现这一点，代码如下，但要非常小心，它是递归的，实际上可能会导致计算器溢出:)
function addElements(&$xml,$array)
{
$params=array();
foreach($array as $k=>$v)
{
if(is_array($v))
addElements($xml->addChild($k), $v);
else $xml->addAttribute($k,$v);
}
}
function xml_encode($array)
{
if(!is_array($array))
trigger_error("Type missmatch xml_encode",E_USER_ERROR);
$xml=new SimpleXMLElement('<?xml version=\'1.0\' encoding=\'utf-8\'?><'.key($array).'/>');
addElements($xml,$array[key($array)]);
return $xml->asXML();
}
您可能希望添加对数组长度的检查，以便将某些元素设置在数据部分内而不是作为属性。
