如何在PHP中将xml转换为数组？
我想把下面的XML转换成PHP数组。 有关如何做到这一点的任何建议？
<aaaa Version="1.0"> <bbb> <cccc> <dddd Id="id:pass" /> <eeee name="hearaman" age="24" /> </cccc> </bbb> </aaaa> 另一种选择是SimpleXML扩展（我相信它是大多数php安装的标准）。
http://php.net/manual/en/book.simplexml.php
对于你的例子，语法看起来像这样
$xml = new SimpleXMLElement($xmlString); echo $xml->bbb->cccc->dddd['Id']; echo $xml->bbb->cccc->eeee['name']; // or........... foreach ($xml->bbb->cccc as $element) { foreach($element as $key => $val) { echo "{$key}: {$val}"; } }
简单！
$xml = simplexml_load_string($xmlstring, "SimpleXMLElement", LIBXML_NOCDATA); $json = json_encode($xml); $array = json_decode($json,TRUE);
将XML字符串（ $buffer ）转换为一个简化的数组，忽略属性并用相同的名称对子元素进行分组：
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，则可以通过SimpleXMLElement的JSON编码/解码来使用它们。 这通常是最简单的快速解决方案：
$xml = simplexml_load_string($buffer); $array = json_decode(json_encode((array) $xml), 1); $array = array($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，所有这些方法只能在XML文档的命名空间中使用。
$array = json_decode(json_encode((array)simplexml_load_string($xml)),1);
惊讶没有人提到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);

请参考这个
使用我给出的答案在下面的问题，它会工作很好。
在那里用$替换$ ssString的值
"<aaaa Version="1.0"><bbb><ccc><dddd Id="id:pass" /><eeee name="hearaman" age="24" /></cccc></bbb></aaa>"
如果有任何不便告诉我。

我喜欢这个问题，一些答案对我有帮助，但我需要将XML转换为一个统治数组，所以我会张贴我的解决方案，也许有人需要它以后：
<?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; } ?>
遇到只有文本节点的子元素时，接受的答案中使用的方法删除属性。 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（我希望我可以在这里给予信任，因为我确定我是从某种东西改编的）：
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 ) ) ) ) )
