Php 防止SimpleXML合并重复的元素/标记？
我有一些来自avendor的带有重复元素的非标准XML SimpleXML和DOM都在合并我的XML标记。我怎样才能防止这种情况 有没有一种方法可以在不合并它们的情况下将它们放入一个数组 我的XML是这样的：Php 防止SimpleXML合并重复的元素/标记？,php,arrays,xml,dom,simplexml,Php,Arrays,Xml,Dom,Simplexml,我有一些来自avendor的带有重复元素的非标准XML SimpleXML和DOM都在合并我的XML标记。我怎样才能防止这种情况 有没有一种方法可以在不合并它们的情况下将它们放入一个数组 我的XML是这样的： 什么是1+1？ 2. 4. 1. 0 0 > 1? 真的 假的 什么是2+1？ 3. 4. 1. 0 我的PHP是这样的： 发生了什么事？ 无论我如何尝试，SimpleXML都会将元素合并成一个数组（），如下所示： [questions] => Array ( [mult

$dom->loadXML($xml);
$questions = $dom->getElementsByTagName('questions')->item(0);

井然有序：

array(1) {
'id' =>
string(1) "1"

}
}

public $directions =>
string(6) "0 > 1?"

}
string(14) "multiplechoice"
class SimpleXMLElement#4 (3) {
public $@attributes =>

正如包括我在内的其他人所概述的，不可能按照您在问题中要求的方式将树结构放入数组中 XML是一种树状结构，同一级别上可以存在多个同名元素。这是数组不可能实现的 因此，最好保持simplexmlement的原样。与处理阵列相比，它们在数据上的操作要舒服得多 然而，仍然可以用这些数据创建一个类似于您所要求的数组，但需要对其中的结构进行特殊处理。没有通用的方法来处理这个问题 例如：问题中的所有子元素位于其位置，然后键入其名称：
$result = $xml->xpath('//questions/*');
foreach ($result as &$rebuild) {
$rebuild = [$rebuild->getName() => $rebuild];
}
unset($rebuild);
$result = ['questions' => $result];
$array = json_decode(json_encode($result), true);

当然这是正常的，你不能有重复的密钥，所以它会将它们合并到其中。我的问题不是这样做是否正确，而是是否有可能解决这个问题。我一直在使用供应商提供的非标准XML…在数组/哈希映射中不能使用它。如果需要按顺序排列内容，请不要将其转换为那样的命名数组。如果您需要比简单XML提供更多的功能，请选择
