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>

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;
}
?>
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));
Array
(
[aaaa] => Array
(
[@attributes] => Array
(
[Version] => 1.0
)
[bbb] => Array
(
[cccc] => Array
(
[dddd] => Array
(
[@attributes] => Array
(
[id] => 123
)
)
[eeee] => Array
(
[@attributes] => Array
(
[name] => john
[age] => 24
)
)
[ffff] => Array
(
[@attributes] => Array
(
[type] => employee
)
[_value] => Supervisor
)
)
)
)
)
将一个XML字符串($buffer)转换为一个忽略属性的简化数组，并将具有相同名称的子元素分组:
function XML2Array(SimpleXMLElement $parent)
{
$array = array();
foreach ($parent as $name => $element) {
($node = & $array[$name])
&& (1 === count($node) ? $node = array($node) : 1)
&& $node = & $node[];
$node = $element->count() ? XML2Array($element) : trim($element);
}
return $array;
}
$xml = simplexml_load_string($buffer);
$array = XML2Array($xml);
$array = array($xml->getName() => $array);
结果:
Array
(
[aaaa] => Array
(
[bbb] => Array
(
[cccc] => Array
(
[dddd] =>
[eeee] =>
)
)
)
)
如果您还想拥有这些属性，可以通过SimpleXMLElement的JSON编码/解码使用它们。这通常是最简单快捷的解决方法:
$xml = simplexml_load_string($buffer);
$array = json_decode(json_encode((array) $xml), true);
$array = array($xml->getName() => $array);
结果:
Array
(
[aaaa] => Array
(
[@attributes] => Array
(
[Version] => 1.0
)
[bbb] => Array
(
[cccc] => Array
(
[dddd] => Array
(
[@attributes] => Array
(
[Id] => id:pass
)
)
[eeee] => Array
(
[@attributes] => Array
(
[name] => hearaman
[age] => 24
)
)
)
)
)
)
请注意，所有这些方法都只能在XML文档的名称空间中工作。
简单!
$xml = simplexml_load_string($xmlstring, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
