以下代码用于将MySQL表中的数据导出为XML文件。我尝试了几个代码,但没有得到结果。请检查并帮助我。

<?php
require_once "classes/dbconnection-class.php";
if(isset($_POST['export'])){
header('Content-type: text/xml');
$xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
$root_element = "addressbook"; //fruits
$xml .= "<$root_element>";
$query = "SELECT AB.id, AB.name, AB.firstname, AB.street, AB.zipcode, AB.city_id, CI.city FROM address_book AS AB INNER JOIN city AS CI ON AB.city_id = CI.id";
$result = $mysqli->query($query);
if (!$result) {
die('Invalid query: ' . $mysqli->error());
}
while($result_array = $result->fetch_assoc()){
$xml .= "<address>";
foreach($result_array as $key => $value)
{
//$key holds the table column name
$xml .= "<$key>";
//embed the SQL data in a CDATA element to avoid XML entity issues
$xml .= "<![CDATA[$value]]>";
//and close the element
$xml .= "</$key>";
}
$xml.="</address>";
}
$xml .= "</$root_element>";
header ("Content-Type:text/xml");
//header('Content-Disposition: attachment; filename="downloaded.xml"');
echo $xml;

这样显示 XML,它只会显示标签内的值。但是,如果您查看页面源代码,您将看到完整生成的 XML。 - Armen
