Array
(
    [0] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [id] => 1
                )

            [timecode] => 12:23:55:142
            [datetimecode] => 11:30:01:06 2016/10/14
            [color] => Green
            [user] => logger 1
            [comment] => Jdjd
            [framecode] => 1115899
        )

    [1] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [id] => 2
                )

            [timecode] => 06:12:04:02

            [color] => Magenta
            [user] => logger 1
            [comment] => Ndnnd
Ndnnd
            [framecode] => 558109

        (
            [@attributes] => Array
                (

                )

            [timecode] => 06:12:13:17

我通过谷歌搜索找到的

How to convert array to SimpleXML

您有一组简单的 SimpleXMLElement 对象

所以

$xml = new SimpleXMLElement('<root/>');
foreach ($my_array as $key => $value) {
    $node = "node" . $key;
    $xml->addChild($node, $value);
}

应该添加 , ,

如果 $value 表现良好。我没有测试。
