The example of this article describes the method of using PHP to store XML data into an array using DOM. Share it with everyone for your reference, the details are as follows:

<?php
$doc = new DOMDocument(&#39;1.0&#39;,&#39;utf-8&#39;);
$doc->load("config.xml");
$roots=$doc->documentElement;//获取根节点也就是config（仅有一个）
$childs=$roots->childNodes;//获取根节点下所有子节点也就是 db smarty
for($i=0;$i<$childs->length;$i++){ //按照根节点下的子节点数量进行循环存入数组
 $config_item=$childs->item($i); //具体获得db smarty
 $configs[$config_item->nodeName]=array();//将db smarty这两个子节点的名称作为数据存入数组中
 $items=$config_item->childNodes; //获得db smarty下的所有子节点
 for($j=0;$j<$items->length;$j++){//按照db smarty下所有子节点数进行循环将db smarty下的子节点名与值以二维数组存入
 $item=$items->item($j);   //通过循环获取每个db smarty 下的子节点
 $configs[$config_item->nodeName][$item->nodeName]=$item->nodeValue;
 }//二维数组的书写
 }
var_dump($configs);
