将内容类型设置为XML，以便浏览器将其识别为XML.

Set the content type to be XML, so that the browser will recognise it as XML.

header( "content-type: application/xml; charset=ISO-8859-15" );

在您的代码中将其更改为:

In your code Change it to:

// Set the content type to be XML, so that the browser will   recognise it as XML.
header( "content-type: application/xml; charset=ISO-8859-15" );

// "Create" the document.
$doc = new DOMDocument( "1.0", "ISO-8859-15" );

+++我认为您可以做类似的事情

+++I think you can do something like this

<root>
<?
   foreach ( $row as $fieldname => $fieldvalue){
    ?>
    <events>
        <fieldname><?=fieldname; ?></fieldname>
        <fieldvalue><?=$fieldvalue; ?></fieldvalue>
    </events>
    }
?>
</root>
