将XMLWriter输出到XML文件

Question

我目前正在使用XMLWriter来显示xml文件.但是,我想知道如何将输出导出到.xml文件.

我目前的代码是:

$res = mysql_query($sql);

$xml = new XMLWriter();

$xml->openURI("php://output");
$xml->startDocument();
$xml->startElement('stores');

while ($row = mysql_fetch_assoc($res)) {
//loads of code
}
$xml->endElement();

$xml->flush();

Answer 1

使用一个文件名,而不是php://output在openURI()方法.

$writer = new XMLWriter();
$writer->openURI('test.xml');
$writer->startDocument("1.0");
$writer->startElement("greeting");
$writer->text('Hello World');
$writer->endDocument();
$writer->flush();
