我以为我可以从mysql查询中的php脚本中正确创建xml文档,但是即使mysql查询有效,我也没有得到xml文档作为回报(没有任何php错误对我有帮助)!
<?php
...
$result = $mysqli->query($sql);
if ($result) { //this query works, but no xml document produced as a result
$d = new DOMDocument();
$books = $d->createElement('hey');
$hey->setAttribute('check','The Adventures of Tom Sawyer');
$d->appendChild($books);
$d->appendChild($hey);
$d->appendChild($books);
echo $d->saveXML();
}
?>
最佳答案
$d->setAttribute('check','The Adventures of Tom Sawyer');
$ d是DOMDocument对象,没有DOMDocument :: setAttribute()方法。
使用DOMElement::setAttribute()或DOMDocument::createAttribute()
if ($result) {
$d = new DOMDocument();
$books = $d->createElement('hey');
$books->setAttribute('check','The Adventures of Tom Sawyer');
$d->appendChild($books);
echo $d->saveXML();
}
