当我尝试查看动态生成的 (PHP) XML 文档时出现此错误:

XML 解析错误:文档元素后出现垃圾 地址:http://dev.leisurepublishing.com/vtc/master.xml.php 第 17 行，第 1 列: ^

我用谷歌搜索并查看了文档，但我无法弄清楚哪里出了问题，有人可以帮我找出问题所在吗？

<?php

header("Content-type: text/xml");
require_once("admin/assets/db_connect.php");

echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
?>

require_once("admin/assets/db_disconnect.php");

最佳答案

删除除xml 之外的所有PHP header 标签并添加:

<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />
</head>
