如何将数组转换为PHP中的SimpleXML对象?
当前回答
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);

<?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();
这是我的入口,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);
您也可以通过DOM来实现这一点。请参阅下面的代码。
<?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);
}
}
?>
我认为上面所有的解决方案都很好,但我看到目前为止,它并没有真正创建一个准确的格式良好的XML,因为数组键与$my_array[main_node][multiple_values][] = ARRAY ('id' => '1')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解析器方面的一个问题……
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>
如果你用load_simple_xml来解析…你会得到完全相同的数组/对象结构。
我的函数还自动创建正确的根节点。
// Code to convert php array to xml document 20211112
function array2xml(array $data, $xml_class_obj = '', $group_by_parent_allowed = '', $options = array())
{
if(!$xml_class_obj) :
$is_root = 1;
$xml_class_obj = new XMLWriter();
$xml_class_obj->openMemory();
$xml_class_obj->setIndent(TRUE);
$xml_class_obj->setIndentString(' ');
if($options['encoding'] != '') $xml_class_obj->startDocument('1.0', $options['encoding']);
else $xml_class_obj->startDocument('1.0');
endif;
foreach ($data as $key => $value) {
if (is_array($value)) { // IS ARRAY
// check if allow below keys are int, if yes group them to same parent tree
$group_by_parent = $key;
foreach(array_keys($value) as $c_keys) :
if(!is_int($c_keys)) $group_by_parent = '';
endforeach;
if(empty($group_by_parent)) $xml_class_obj->startElement($key);
if($group_by_parent_allowed != '') $xml_class_obj->startElement($group_by_parent_allowed);
$this->array2xml($value, $xml_class_obj, $group_by_parent, $options);
if(empty($group_by_parent)) $xml_class_obj->endElement();
} else { // IS VALUE
if(is_string($value)) :
$xml_class_obj->startElement($key);
$xml_class_obj->writeCData($value);
$xml_class_obj->endElement();
else :
$xml_class_obj->writeElement($key, $value);
endif;
}
} // foreach
if($group_by_parent_allowed != '') $xml_class_obj->endElement();
if($is_root == 1) :
$xml_class_obj->endDocument();
return $xml_class_obj->outputMemory();
else :
return $xml_class_obj;
endif;
}
// usage
$ary_new_xml = array();
$ary_new_xml['order']['customer']['customerid'] = '123456';
$ary_new_xml['order']['customer']['customertype'] = 15;
$ary_new_xml['order']['orderprio'] = 2;
$ary_new_xml['order']['orderpos'][] = array('sku' => 9999910001111, 'quantity' => 3);
$ary_new_xml['order']['orderpos'][] = array('sku' => 9999910002222, 'quantity' => 1);
echo array2xml($ary_new_xml,'','',array('enconding' => 'UTF-8'));
结果:
<?xml version="1.0" encoding="UTF-8"?>
<order>
<customer>
<customerid>82936639</customerid>
<customertype>15</customertype>
</customer>
<orderprio>2</orderprio>
<orderpos>
<sku>9999910001111</sku>
<quantity>3</quantity>
</orderpos>
<orderpos>
<sku>9999910002222</sku>
<quantity>1</quantity>
</orderpos>
</order>
我希望这能帮助到一些人;)
只是对上面的函数进行了编辑,当键是数字时,添加前缀“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");
}
}
}
}
