如何在 PHP 中将数组转换为 SimpleXML 对象?
34 回答
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 将如下所示:
<?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 defination to convert array to xml
function array_to_xml( $data, &$xml_data ) {
foreach( $data as $key => $value ) {
if( is_array($value) ) {
if( is_numeric($key) ){
$key = 'item'.$key; //dealing with <0/>..<n/> issues
}
$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');
?>
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>
键和值被交换 - 你可以array_flip()
在 array_walk 之前修复它。array_walk_recursive
需要 PHP 5。你可以array_walk
改用,但你不会进入'stack' => 'overflow'
xml。
此处提供的答案仅将数组转换为带有节点的 XML,您无法设置属性。我编写了一个 php 函数,它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,很少有约定(只有当你想使用属性时)
以下示例也允许您在 XML 中设置属性。
源代码可以在这里找到: https ://github.com/digitickets/lalit/blob/master/src/Array2XML.php
<?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 != 0 && $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,它基于您编写的数组。
print $xml->asXML();
<?php 函数array_to_xml(数组$arr,SimpleXMLElement $xml) { foreach ($arr as $k => $v) { is_array($v) ? array_to_xml($v, $xml->addChild($k)) : $xml->addChild($k, $v); } 返回 $xml; } $test_array = 数组 ( 'bla' => 'blub', 'foo' => '酒吧', 'another_array' => 数组 ( '堆栈' => '溢出', ), ); echo array_to_xml($test_array, new SimpleXMLElement('<root/>'))->asXML();
从 PHP 5.4
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();
}
另一个改进:
/**
* 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');
这是我的条目,简单干净..
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...我拿了小野的代码(谢谢!)并添加了在 XML 中重复标签的能力,它还支持属性,希望有人觉得它有用!
<?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 $dom->saveXml();
?>
我想要一个代码,它将获取数组中的所有元素并将它们视为属性,并将所有数组视为子元素。
所以对于像
array (
'row1' => array ('head_element' =>array("prop1"=>"some value","prop2"=>array("empty"))),
"row2"=> array ("stack"=>"overflow","overflow"=>"overflow")
);
我会得到这样的东西
<?xml version="1.0" encoding="utf-8"?>
<someRoot>
<row1>
<head_element prop1="some value">
<prop2 0="empty"/>
</head_element>
</row1>
<row2 stack="overflow" overflow="stack"/>
</someRoot>
为了实现这一点,代码如下,但要非常小心,它是递归的,实际上可能会导致 stackoverflow :)
function addElements(&$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 $xml->asXML();
}
您可能希望添加对数组长度的检查,以便在数据部分中设置某些元素而不是作为属性。
我使用了我不久前写的几个函数来生成 xml 以从 PHP 和 jQuery 等来回传递......既不使用任何其他框架,也只是纯粹生成一个字符串,然后可以与 SimpleXML(或其他框架)一起使用)...
如果它对任何人有用,请使用它:)
function generateXML($tag_in,$value_in="",$attribute_in=""){
$return = "";
$attributes_out = "";
if (is_array($attribute_in)){
if (count($attribute_in) != 0){
foreach($attribute_in as $k=>$v):
$attributes_out .= " ".$k."=\"".$v."\"";
endforeach;
}
}
return "<".$tag_in."".$attributes_out.((trim($value_in) == "") ? "/>" : ">".$value_in."</".$tag_in.">" );
}
function arrayToXML($array_in){
$return = "";
$attributes = array();
foreach($array_in as $k=>$v):
if ($k[0] == "@"){
// attribute...
$attributes[str_replace("@","",$k)] = $v;
} else {
if (is_array($v)){
$return .= generateXML($k,arrayToXML($v),$attributes);
$attributes = array();
} else if (is_bool($v)) {
$return .= generateXML($k,(($v==true)? "true" : "false"),$attributes);
$attributes = array();
} else {
$return .= generateXML($k,$v,$attributes);
$attributes = array();
}
}
endforeach;
return $return;
}
爱所有 :)
您可以使用我一直在研究的XMLParser 。
$xml = XMLParser::encode(array(
'bla' => 'blub',
'foo' => 'bar',
'another_array' => array (
'stack' => 'overflow',
)
));
// @$xml instanceof SimpleXMLElement
echo $xml->asXML();
会导致:
<?xml version="1.0"?>
<root>
<bla>blub</bla>
<foo>bar</foo>
<another_array>
<stack>overflow</stack>
</another_array>
</root>
基于此处的所有其他内容,通过前缀处理数字索引 + 属性@
,并且可以将 xml 注入现有节点:
代码
function simple_xmlify($arr, SimpleXMLElement $root = null, $el = 'x') {
// based on, among others http://stackoverflow.com/a/1397164/1037948
if(!isset($root) || null == $root) $root = new SimpleXMLElement('<' . $el . '/>');
if(is_array($arr)) {
foreach($arr as $k => $v) {
// special: attributes
if(is_string($k) && $k[0] == '@') $root->addAttribute(substr($k, 1),$v);
// normal: append
else simple_xmlify($v, $root->addChild(
// fix 'invalid xml name' by prefixing numeric keys
is_numeric($k) ? 'n' . $k : $k)
);
}
} else {
$root[0] = $arr;
}
return $root;
}//-- fn simple_xmlify
用法
// lazy declaration via "queryparam"
$args = 'hello=4&var[]=first&var[]=second&foo=1234&var[5]=fifth&var[sub][]=sub1&var[sub][]=sub2&var[sub][]=sub3&var[@name]=the-name&var[@attr2]=something-else&var[sub][@x]=4.356&var[sub][@y]=-9.2252';
$q = array();
parse_str($val, $q);
$xml = simple_xmlify($q); // dump $xml, or...
$result = get_formatted_xml($xml); // see below
结果
<?xml version="1.0"?>
<x>
<hello>4</hello>
<var name="the-name" attr2="something-else">
<n0>first</n0>
<n1>second</n1>
<n5>fifth</n5>
<sub x="4.356" y="-9.2252">
<n0>sub1</n0>
<n1>sub2</n1>
<n2>sub3</n2>
</sub>
</var>
<foo>1234</foo>
</x>
奖励:格式化 XML
function get_formatted_xml(SimpleXMLElement $xml, $domver = null, $preserveWhitespace = true, $formatOutput = true) {
// http://stackoverflow.com/questions/1191167/format-output-of-simplexml-asxml
// create new wrapper, so we can get formatting options
$dom = new DOMDocument($domver);
$dom->preserveWhiteSpace = $preserveWhitespace;
$dom->formatOutput = $formatOutput;
// now import the xml (converted to dom format)
/*
$ix = dom_import_simplexml($xml);
$ix = $dom->importNode($ix, true);
$dom->appendChild($ix);
*/
$dom->loadXML($xml->asXML());
// print
return $dom->saveXML();
}//-- fn get_formatted_xml
如果数组是关联的并且键控正确,那么首先将其转换为 xml 可能会更容易。就像是:
function array2xml ($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您的基本 xml,例如
$simple_xml = simplexml_load_string("<array></array>");
然后对于数组的每个部分,使用类似于我的文本创建循环的东西,而不是对数组的每个节点使用 simplexml 函数“addChild”。
我稍后会尝试并用这两个版本更新这篇文章。
这是一个对我有用的函数:
只需用类似的东西调用它
echo arrayToXml("response",$arrayIWantToConvert);
function arrayToXml($thisNodeName,$input){
if(is_numeric($thisNodeName))
throw new Exception("cannot parse into xml. remainder :".print_r($input,true));
if(!(is_array($input) || is_object($input))){
return "<$thisNodeName>$input</$thisNodeName>";
}
else{
$newNode="<$thisNodeName>";
foreach($input as $key=>$value){
if(is_numeric($key))
$key=substr($thisNodeName,0,strlen($thisNodeName)-1);
$newNode.=arrayToXml3($key,$value);
}
$newNode.="</$thisNodeName>";
return $newNode;
}
}
我发现这个解决方案类似于原始问题
<?php
$test_array = array (
'bla' => 'blub',
'foo' => 'bar',
'another_array' => array (
'stack' => 'overflow',
),
);
class NoSimpleXMLElement extends SimpleXMLElement {
public function addChild($name,$value) {
parent::addChild($value,$name);
}
}
$xml = new NoSimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML();
上面的大部分答案都是正确的。但是,我想出了这个答案,它解决了 array_walk_recursive 兼容性问题以及数字键问题。它还通过了我所做的所有测试:
function arrayToXML(Array $array, SimpleXMLElement &$xml) {
foreach($array as $key => $value) {
// None array
if (!is_array($value)) {
(is_numeric($key)) ? $xml->addChild("item$key", $value) : $xml->addChild($key, $value);
continue;
}
// Array
$xmlChild = (is_numeric($key)) ? $xml->addChild("item$key") : $xml->addChild($key);
arrayToXML($value, $xmlChild);
}
}
我还为此添加了一个测试类,您可能会发现它很有用:
class ArrayToXmlTest extends PHPUnit_Framework_TestCase {
public function setUp(){ }
public function tearDown(){ }
public function testFuncExists() {
$this->assertTrue(function_exists('arrayToXML'));
}
public function testFuncReturnsXml() {
$array = array(
'name' => 'ardi',
'last_name' => 'eshghi',
'age' => 31,
'tel' => '0785323435'
);
$xmlEl = new SimpleXMLElement('<root/>');
arrayToXml($array, $xmlEl);
$this->assertTrue($xmlEl instanceOf SimpleXMLElement);
}
public function testAssocArrayToXml() {
$array = array(
'name' => 'ardi',
'last_name' => 'eshghi',
'age' => 31,
'tel' => '0785323435'
);
$expectedXmlEl = new SimpleXMLElement('<root/>');
$expectedXmlEl->addChild('name', $array['name']);
$expectedXmlEl->addChild('last_name', $array['last_name']);
$expectedXmlEl->addChild('age', $array['age']);
$expectedXmlEl->addChild('tel', $array['tel']);
$actualXmlEl = new SimpleXMLElement('<root/>');
arrayToXml($array, $actualXmlEl);
$this->assertEquals($expectedXmlEl->asXML(), $actualXmlEl->asXML());
}
public function testNoneAssocArrayToXml() {
$array = array(
'ardi',
'eshghi',
31,
'0785323435'
);
// Expected xml value
$expectedXmlEl = new SimpleXMLElement('<root/>');
foreach($array as $key => $value)
$expectedXmlEl->addChild("item$key", $value);
// What the function produces
$actualXmlEl = new SimpleXMLElement('<root/>');
arrayToXml($array, $actualXmlEl);
$this->assertEquals($expectedXmlEl->asXML(), $actualXmlEl->asXML());
}
public function testNestedMixArrayToXml() {
$testArray = array(
"goal",
"nice",
"funny" => array(
'name' => 'ardi',
'tel' =>'07415517499',
"vary",
"fields" => array(
'small',
'email' => 'ardi.eshghi@gmail.com'
),
'good old days'
),
"notes" => "come on lads lets enjoy this",
"cast" => array(
'Tom Cruise',
'Thomas Muller' => array('age' => 24)
)
);
// Expected xml value
$expectedXmlEl = new SimpleXMLElement('<root/>');
$expectedXmlEl->addChild('item0', $testArray[0]);
$expectedXmlEl->addChild('item1', $testArray[1]);
$childEl = $expectedXmlEl->addChild('funny');
$childEl->addChild("name", $testArray['funny']['name']);
$childEl->addChild("tel", $testArray['funny']['tel']);
$childEl->addChild("item0", "vary");
$childChildEl = $childEl->addChild("fields");
$childChildEl->addChild('item0', 'small');
$childChildEl->addChild('email', $testArray['funny']['fields']['email']);
$childEl->addChild("item1", 'good old days');
$expectedXmlEl->addChild('notes', $testArray['notes']);
$childEl2 = $expectedXmlEl->addChild('cast');
$childEl2->addChild('item0', 'Tom Cruise');
$childChildEl2 = $childEl2->addChild('Thomas Muller');
$childChildEl2->addChild('age', $testArray['cast']['Thomas Muller']['age']);
// What the function produces
$actualXmlEl = new SimpleXMLElement('<root/>');
arrayToXml($testArray, $actualXmlEl);
$this->assertEquals($expectedXmlEl->asXML(), $actualXmlEl->asXML());
}
}
其他解决方案:
$marray=array(....);
$options = array(
"encoding" => "UTF-8",
"output_type" => "xml",
"version" => "simple",
"escaping" => array("non-ascii, on-print, markup")
);
$xmlres = xmlrpc_encode_request('root', $marray, $options);
print($xmlres);
只是对上面一个函数的编辑,当一个键是数字时,添加一个前缀“key_”
// initializing or creating array
$student_info = array(your array data);
// creating object of SimpleXMLElement
$xml_student_info = new SimpleXMLElement("<?xml version=\"1.0\"?><student_info></student_info>");
// function call to convert array to xml
array_to_xml($student,$xml_student_info);
//saving generated xml file
$xml_student_info->asXML('file path and name');
function array_to_xml($student_info, &$xml_student_info) {
foreach($student_info as $key => $value) {
if(is_array($value)) {
if(!is_numeric($key)){
$subnode = $xml_student_info->addChild("$key");
array_to_xml($value, $subnode);
}
else{
$subnode = $xml_student_info->addChild("key_$key");
array_to_xml($value, $subnode);
}
}
else {
if(!is_numeric($key)){
$xml_student_info->addChild("$key","$value");
}else{
$xml_student_info->addChild("key_$key","$value");
}
}
}
}
您可以直接在代码中使用以下函数,
function artoxml($arr, $i=1,$flag=false){
$sp = "";
for($j=0;$j<=$i;$j++){
$sp.=" ";
}
foreach($arr as $key=>$val){
echo "$sp<".$key.">";
if($i==1) echo "\n";
if(is_array($val)){
if(!$flag){echo"\n";}
artoxml($val,$i+5);
echo "$sp</".$key.">\n";
}else{
echo "$val"."</".$key.">\n";
}
}
}
使用第一个参数作为数组调用函数,第二个参数必须为 1,这将增加完美缩进,第三个必须为真。
例如,如果要转换的数组变量是$array1,那么调用就是,调用函数应该用<pre>
标签封装。
artoxml($array1,1,true);
执行文件后请查看页面源代码,因为 < 和 > 符号不会显示在 html 页面中。
function toXML($data, $obj = false, $dom) {
$is_first_level = false;
if($obj === false) {
$dom = new DomDocument('1.0');
$obj = $dom;
$is_first_level = true;
}
if(is_array($data)) {
foreach($data as $key => $item) {
$this->toXML($item, $obj->appendChild($dom->createElement($key)), $dom);
}
}else {
$obj->appendChild($dom->createTextNode($data));
}
if($is_first_level) {
$obj->formatOutput = true;
return $obj->saveXML();
}
return $obj;
}
function array2xml(array $data, SimpleXMLElement $object = null, $oldNodeName = 'item')
{
if (is_null($object)) $object = new SimpleXMLElement('<root/>');
$isNumbered = true;
$idx = 0;
foreach ($data as $key => $x)
if (is_string($key) || ($idx++ != $key + 0))
$isNumbered = false;
foreach ($data as $key => $value)
{
$attribute = preg_match('/^[0-9]/', $key . '') ? $key : null;
$key = (is_string($key) && !preg_match('/^[0-9]/', $key . '')) ? $key : preg_replace('/s$/', '', $oldNodeName);
if (is_array($value))
{
$new_object = $object->addChild($key);
if (!$isNumbered && !is_null($attribute)) $new_object->addAttribute('id', $attribute);
array2xml($value, $new_object, $key);
}
else
{
if (is_bool($value)) $value = $value ? 'true' : 'false';
$node = $object->addChild($key, htmlspecialchars($value));
if (!$isNumbered && !is_null($attribute) && !isset($node->attributes()->id))
$node->addAttribute('id', $attribute);
}
}
return $object;
}
例如,此函数返回数字索引的 <obj>...</obj><obj>...</obj> XML 标记列表。
输入:
array(
'people' => array(
'dog',
'cat',
'life' => array(
'gum',
'shoe',
),
'fish',
),
array('yeah'),
)
输出:
<root>
<people>
<people>dog</people>
<people>cat</people>
<life>
<life>gum</life>
<life>shoe</life>
</life>
<people>fish</people>
<people>
<people>yeah</people>
</people>
</people>
</root>
这应该满足所有常见的需求。也许您可以将第 3 行更改为:
$key = is_string($key) ? $key : $oldNodeName . '_' . $key;
或者,如果您正在使用以 s 结尾的复数:
$key = is_string($key) ? $key : preg_replace('/s$/', '', $oldNodeName);
使用FluidXML,您可以从PHP Array开始生成SimpleXML的 XML,只需两行代码。
$fluidxml = fluidxml($array);
$simplexml = simplexml_import_dom($fluidxml->dom());
一个示例数组可以是
$array = [ 'doc' => [
'fruit' => 'orange',
'cake' => [
'@id' => '123',
'@' => 'tiramisu' ],
[ 'pasta' => 'matriciana' ],
[ 'pasta' => 'boscaiola' ]
] ];
如果详细的 xml 不是问题,您可以使用 xmlrpc_encode 从数组创建 xml。 www.php.net/xmlrpc_encode
如果您使用关联键和/或数字键,请注意创建的 xml 会有所不同
<?php
// /params/param/value/struct/member
// there is a tag "member" for each element
// "member" contains a tag "name". its value is the associative key
$xml1 = xmlrpc_encode(array('a'=>'b','c'=>'d'));
$simplexml1 = simplexml_load_string($xml1);

我的答案,拼凑别人的答案。这应该可以纠正无法补偿数字键的问题:
function array_to_xml($array, $root, $element) {
$xml = new SimpleXMLElement("<{$root}/>");
foreach ($array as $value) {
$elem = $xml->addChild($element);
xml_recurse_child($elem, $value);
}
return $xml;
}
function xml_recurse_child(&$node, $child) {
foreach ($child as $key=>$value) {
if(is_array($value)) {
foreach ($value as $k => $v) {
if(is_numeric($k)){
xml_recurse_child($node, array($key => $v));
}
else {
$subnode = $node->addChild($key);
xml_recurse_child($subnode, $value);
}
}
}
else {
$node->addChild($key, $value);
}
}
}
该array_to_xml()
函数假定数组首先由数字键组成。如果你的数组有一个初始元素,你会从函数中删除foreach()
and$elem
语句并直接传递。array_to_xml()
$xml
我会评论第二个投票最多的答案,因为如果有数字索引的内部数组,它不会保留结构并生成错误的 xml。
我基于它开发了自己的版本,因为无论数据结构如何,我都需要 json 和 xml 之间的简单转换器。我的版本保留了原始数组的数字键信息和结构。它通过将值包装到具有包含数字键的键属性的值命名元素来为数字索引值创建元素。
例如
array('test' => array(0 => 'some value', 1 => 'other'))
转换为
<test><value key="0">some value</value><value key="1">other</value></test>
我的 array_to_xml -function 版本(希望它可以帮助某人:)
function array_to_xml($arr, &$xml) {
foreach($arr as $key => $value) {
if(is_array($value)) {
if(!is_numeric($key)){
$subnode = $xml->addChild("$key");
} else {
$subnode = $xml->addChild("value");
$subnode->addAttribute('key', $key);
}
array_to_xml($value, $subnode);
}
else {
if (is_numeric($key)) {
$xml->addChild("value", $value)->addAttribute('key', $key);
} else {
$xml->addChild("$key",$value);
}
}
}
}
整个 XML 结构在 $data 数组中定义:
function array2Xml($data, $xml = null)
{
if (is_null($xml)) {
$xml = simplexml_load_string('<' . key($data) . '/>');
$data = current($data);
$return = true;
}
if (is_array($data)) {
foreach ($data as $name => $value) {
array2Xml($value, is_numeric($name) ? $xml : $xml->addChild($name));
}
} else {
$xml->{0} = $data;
}
if (!empty($return)) {
return $xml->asXML();
}
}
如果你在 magento 工作并且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;
}
}

你也可以通过 DOM 做到这一点。请看下面的代码。
<?php
$el = array();
$command = array();
$dom = new DOMDocument('1.0', 'utf-8');
$dom->formatOutput = true;
$xml_array = [
'root'=>[
'Good guy' => [
'name' => [
'_cdata' => 'Luke Skywalker'
],
'weapon' => 'Lightsaber'
],
'Bad guy' => [
'name' => 'Sauron',
'weapon' => 'Evil Eye'
]
]
];
convert_xml($xml_array);
if(!empty($el))
{
$dom->appendChild(end($el));
}
echo $dom->saveXML();
?>
<?php
function convert_xml($Xml)
{
global $el, $dom;
foreach($Xml as $id=>$val)
{
if(is_numeric($id))
{
$id = "Item".($id);
}
$id = str_replace(' ', '-', strtolower($id));
if(is_array($val))
{
$ele = $dom->createElement($id);
array_push($el, $ele);
convert_xml($val);
}
else
{
$ele = $dom->createElement($id, $val);
if(!empty($el))
{
$com = end($el)->appendChild($ele);
}
else
{
$dom->appendChild($ele);
}
}
}
if(sizeof($el) > 1)
{
$child = end($el);
$com = prev($el)->appendChild($child);
array_pop($el);
}
}
?>
我认为上述所有解决方案都很好,但到目前为止我所看到的,它并没有真正创建一个格式良好的 XML,因为带有 $my_array[main_node][multiple_values][] = array('id' => '1' 的 ARRAY Keys ) 然后转换为
<main_node>
<multiple_values>
<0>
<id>1 test</id>
</0>
</multiple_values>
<multiple_values>
<1>
<id>2 test</id>
</1>
</multiple_values>
</main_node>
这是 XML Parser 端的问题......
I should be like this:
<main_node>
<multiple_values>
<id>1 test</id>
</multiple_values>
<multiple_values>
<id>2 test</id>
</multiple_values>
</main_node>
因此,如果您通过 load_simple_xml 解析它...您将返回完全相同的数组/对象结构。
我的功能还会自动创建正确的根节点。

以下处理命名空间。在这种情况下,您构建包装器以包含命名空间定义,并将其传递给函数。使用冒号来标识命名空间。
测试阵列
$inarray = [];
$inarray['p:apple'] = "red";
$inarray['p:pear'] = "green";
$inarray['p:peach'] = "orange";
$inarray['p1:grocers'] = ['p1:local' => "cheap", 'p1:imported' => "expensive"];
$xml = new SimpleXMLElement( '<p:wrapper xmlns:p="http://namespace.org/api" xmlns:p1="http://namespace.org/api2 /> ');
array_to_xml($xml,$inarray);
function array_to_xml(SimpleXMLElement $object, array $data)
{
$nslist = $object->getDocNamespaces();
foreach ($data as $key => $value)
{
$nspace = null;
$keyparts = explode(":",$key,2);
if ( count($keyparts)==2)
$nspace = $nslist[$keyparts[0]];
if (is_array($value))
{
$key = is_numeric($key) ? "item$key" : $key;
$new_object = $object->addChild($key,null,$nspace);
array_to_xml($new_object, $value);
}
else
{
$key = is_numeric($key) ? "item$key" : $key;
$object->addChild($key, $value,$nspace);
}
}
}
您可以使用 Mustache 模板引擎并制作如下模板:
{{#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 中像这样使用它:
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);
