XML解析错误-文档末尾的额外内容

我正在尝试提供获取JSON或XML响应的选项。

JSON可以正常工作，但是当我查看XML时，出现错误。

http://lmsapi.com/?api_key=fba9e59d7af86b239e82581780ff987e&format=json

http://lmsapi.com/?api_key=fba9e59d7af86b239e82581780ff987e&format=xml

我不确定发生了什么问题。我已经搜索过，唯一看到的是确保我的元素名称中没有多余的空格，甚至没有空格，而我没有。

index.php

<?php
require_once('includes/inc.settings.php');
if(${'Response'}['format'] == 'json'){
    print_r(${'Results'});  
}elseif(${'Response'}['format'] == 'xml'){
    header('Content-type: application/xml');
    echo "<?xml version=\"1.0\"?>";
    echo ${'Results'};
}
?>

inc.settings.php

任何帮助将非常感激！

回答：

XML只能有一个“文档实体”或“根”，您正在尝试使用两个（status和format）。将两个元素包装在一个元素中，这样您的XML文档只有一个根元素。

<?xml version="1.0"?>
<status>success</status>
<format>xml</format>

<?xml version="1.0"?>
<response>
  <status>success</status>
  <format>xml</format>
</response>
