如何在php中将值从XML文件添加到csv文件？

$xml = simplexml_load_file('data.xml');

$data = array();
foreach ($xml->children() as $item) {
    $data[] = array(
        'name' => (string)$item->name,
        'age' => (int)$item->age,
        'email' => (string)$item->email
    );
}

$csvFile = fopen('data.csv', 'w');
foreach ($data as $row) {
    fputcsv($csvFile, $row);
}
fclose($csvFile);

$xml = simplexml_load_file('data.xml');

$data = array();
foreach ($xml->children() as $item) {
    $data[] = array(
        'name' => (string)$item->name,
        'age' => (int)$item->age,
        'email' => (string)$item->email
    );
}

$csvFile = fopen('data.csv', 'w');
foreach ($data as $row) {
    fputcsv($csvFile, $row);
}
fclose($csvFile);
