如何对$_FILES (多次上传)数组重新排序？

// 获取上传文件的顺序信息
$uploadOrder = array();
foreach ($_FILES['file']['name'] as $key => $value) {
    $uploadOrder[$key] = $key;
}

// 根据上传顺序信息，构建新的数组
$newFiles = array();
foreach ($uploadOrder as $key) {
    $newFiles['name'][] = $_FILES['file']['name'][$key];
    $newFiles['type'][] = $_FILES['file']['type'][$key];
    $newFiles['tmp_name'][] = $_FILES['file']['tmp_name'][$key];
    $newFiles['error'][] = $_FILES['file']['error'][$key];
    $newFiles['size'][] = $_FILES['file']['size'][$key];
}

// 对新数组进行排序
usort($newFiles['name'], function($a, $b) {
    return strnatcasecmp($a, $b);
});

// 重新构建$_FILES数组
$_FILES['file'] = $newFiles;

// 现在$_FILES数组中的文件已按名称排序
