使用XMLWriter在PHP中生成XML文件 - outputMemory()函数不起作用

我正在尝试使用 XMLWriter 在PHP中创建和编写 XML 文件。

我的代码如下:

$writer = new XMLWriter();
$writer->openURI('php://output');
$writer->startDocument('1.0','UTF-8');
$writer->setIndent(4);
$writer->startElement('items');
$writer->startElement("main");
$writer->writeElement('user_id', 3);
$writer->writeElement('msg_count', 11);
$writer->endElement();
$writer->startElement("msg");
$writer->writeAttribute('category', 'test');
$writer->endElement();
$writer->endElement();
$writer->endDocument();
$writer->flush();

header('Content-type: text/xml');

echo $writer->outputMemory();

这似乎在屏幕上创建了有效的XML

<?xml version="1.0" encoding="UTF-8"?>
<items>
  <main>
    <user_id>3</user_id>
    <msg_count>11</msg_count>
  </main>
  <msg category="test"/>
</items>

但是,当我尝试使用:

回显XML时
echo $writer->outputMemory();

除非使用以下命令创建XML文件,否则输出为空白

$filename = "xml/example.xml";
$file = $writer->outputMemory();
file_put_contents($filename,$file);

文件内容也是空白的。

我如何将XML输出到文件中? outputMemory()函数似乎没有填充。

答案 0 :(得分:1)

您可以尝试使用该代码

$filename = "xml/example.xml";
header("Content-Type: text/html/force-download");
header("Content-Disposition: attachment; filename=".$filename.".xml");

并且不再使用:

$filename = "xml/example.xml";
$file = $writer->outputMemory();
file_put_contents($filename,$file);
