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。

$array = json_decode(json_encode((array)simplexml_load_string($xml)),true);

另一个选择是SimpleXML扩展(我相信它是大多数php安装的标配)。

http://php.net/manual/en/book.simplexml.php

在您的示例中，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}";
  }
}

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;
}
?>
