如何使用PHP将数组打印为Xml

$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
);

$xml = new SimpleXMLElement('<root/>');

foreach ($data as $key => $value) {
    $xml->addChild($key, $value);
}

$xmlString = $xml->asXML();

echo $xmlString;

$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
);

$xml = new SimpleXMLElement('<root/>');

foreach ($data as $key => $value) {
    $xml->addChild($key, $value);
}

$xmlString = $xml->asXML();

echo $xmlString;
