我正在尝试构建一个 PHP 脚本，允许用户编辑谷歌地图的 XML 文件。我的脚本的灵感来自How to modify xml file using PHP

<?php
$xml = new DOMDocument('1.0','UTF-8');
$xml->preserveWhiteSpace = FALSE;
            
$xml->load("file2.xml");
        
$mar = $xml->getElementsByTagName("marker");
foreach($mar as $row){
    
    $name = $row->getElementsByTagName('name')->item(0);
    $lat = $row->getElementsByTagName('lat')->item(0);
    $lng = $row->getElementsByTagName('lng')->item(0);
    $category = $row->getElementsByTagName('category')->item(0);
    $type = $row->getElementsByTagName('type')->item(0);
    $id = $row->getElementsByTagName('id')->item(0);
    $desc = $row->getElementsByTagName('desc')->item(0);
    $img = $row->getElementsByTagName('img')->item(0);

    $row->replaceChild($name, $name);
    $row->replaceChild($lat, $lat);
    $row->replaceChild($lng, $lng);
    $row->replaceChild($category, $category);
    $row->replaceChild($type, $type);
    $row->replaceChild($id, $id);
    $row->replaceChild($desc, $desc);
    $row->replaceChild($img, $img);
?>

XMLfile2.xml

<markers>
   <marker>
     <name>name 12</name>
     <lat>lat 1</lat>
     <lng>lng 1</lng>
     <category>cat 1</category>
     <type>type 1</type>
     <id>id 1</id>
     <desc>desc 1</desc>
     <img>/path/1.png</img>
  </marker>
  <marker>
    <name>name 12</name>

    <id>id 1</id>
    <desc>desc 1</desc>
    <img>/path/1.png</img>
   </marker>
</markers>

我需要引入一个数组或一个计数$i = 0; ...$i++; ，以便能够编辑每个单独的字段并提交更改，并且想知道如何处理它。也许那里有一个工作脚本，你可能知道我可以学习？帮助表示赞赏。谢谢
