使用属性xml php编写元素

我正在使用php编写xml。我想用元素写入属性。我的代码如下

$writer = new XMLWriter();  
$writer->openURI('php://output');   
$writer->startDocument('1.0','UTF-8');   
$writer->setIndent(4);   
$writer->startElement('Response');
$writer->writeElement("Dial","+111111111");
$writer->endElement();
$writer->endDocument();   
$writer->flush();

这就产生了这个输出

<response>
<dial>+111111</dial>
</response>

但这只添加了startElement，而没有添加writeElement。

谢谢你，行

$writer->writeElement（“拨号”，“+111111111”）您应该在某些步骤中编写元素以添加属性

$writer->startElement("Dial");
$writer->writeAttribute('action', "myaction");
$writer->text("+111111111");
$writer->endElement();

改为行
$writer->writeElement（“拨号”，“+111111”）您应该在某些步骤中编写元素以添加属性

$writer->startElement("Dial");
$writer->writeAttribute('action', "myaction");
$writer->text("+111111111");
$writer->endElement();


$writer->startElement("Dial");
$writer->writeAttribute('action', "myaction");
$writer->text("+111111111");
$writer->endElement();
