我想把下面的XML转换成PHP数组。有什么建议吗?
<aaaa Version="1.0">
<bbb>
<cccc>
<dddd Id="id:pass" />
<eeee name="hearaman" age="24" />
</cccc>
</bbb>
</aaaa>

其他回答
当遇到只有文本节点的子元素时，在接受的答案拖放属性中使用的方法。例如:
$xml = '<container><element attribute="123">abcd</element></container>';
print_r(json_decode(json_encode(simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA)),1));
Array
(
[element] => abcd
)
我的解决方案(我希望我能在这里给予赞扬，因为我确信这是从某些东西改编而来的):
function XMLtoArray($xml) {
$previous_value = libxml_use_internal_errors(true);
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->preserveWhiteSpace = false;
$dom->loadXml($xml);
libxml_use_internal_errors($previous_value);
if (libxml_get_errors()) {
return [];
}
return DOMtoArray($dom);
}
function DOMtoArray($root) {
$result = array();
if ($root->hasAttributes()) {
$attrs = $root->attributes;
foreach ($attrs as $attr) {
$result['@attributes'][$attr->name] = $attr->value;
}
}
if ($root->hasChildNodes()) {
$children = $root->childNodes;
if ($children->length == 1) {
$child = $children->item(0);
if (in_array($child->nodeType,[XML_TEXT_NODE,XML_CDATA_SECTION_NODE])) {
$result['_value'] = $child->nodeValue;
return count($result) == 1
? $result['_value']
: $result;
}
}
$groups = array();
foreach ($children as $child) {
if (!isset($result[$child->nodeName])) {
$result[$child->nodeName] = DOMtoArray($child);
} else {
if (!isset($groups[$child->nodeName])) {
$result[$child->nodeName] = array($result[$child->nodeName]);
$groups[$child->nodeName] = 1;
}
$result[$child->nodeName][] = DOMtoArray($child);
}
}
}
return $result;
}
$xml = '
<aaaa Version="1.0">
<bbb>
<cccc>
<dddd id="123" />
<eeee name="john" age="24" />
<ffff type="employee">Supervisor</ffff>
</cccc>
</bbb>
</aaaa>
';
print_r(XMLtoArray($xml));

奇怪的是没有人提到xml_parse_into_struct:
$simple = "<para><note>simple note</note></para>";
$p = xml_parser_create();
xml_parse_into_struct($p, $simple, $vals, $index);
xml_parser_free($p);
echo "Index array\n";
print_r($index);
echo "\nVals array\n";
print_r($vals);

我喜欢这个问题，一些答案对我很有帮助，但我需要将xml转换为一个支配数组，所以我将发布我的解决方案，也许以后有人需要它:
<?php
$xml = json_decode(json_encode((array)simplexml_load_string($xml)),1);
$finalItem = getChild($xml);
var_dump($finalItem);
function getChild($xml, $finalItem = []){
foreach($xml as $key=>$value){
if(!is_array($value)){
$finalItem[$key] = $value;
}else{
$finalItem = getChild($value, $finalItem);
}
}
return $finalItem;
}
?>
