如何在 PHP 中循环一个 SimpleXMLElement 对象休息客户端？

Question

如何循环一个 SimpleXMLElement 对象？这就是我所拥有的：我尝试了多种方式进行迭代，但没有成功：

 Array
 (
    [status] => 1
    [data_nilai_siswa] => SimpleXMLElement Object
    (
        [item] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [id_siswa] => 1
                        [nama_siswa] => 1
                        [n_bahasa] => 1.00
                        [n_matematika] => 1.00
                        [n_binggris] => 1.00
                    )

                [1] => SimpleXMLElement Object
                    (
                        [id_siswa] => 2
                        [nama_siswa] => 2
                        [n_bahasa] => 2.00
                        [n_matematika] => 2.00
                        [n_binggris] => 2.00
                    )
            )
       )
 )

我使用库休息客户端philsturgeon/codeigniter-restclient 和脚本休息客户端：

$xmlResponse = $this->rest->get('http://127.0.0.1/EJ/testclient2/getdata/nilai');
$projects = array();

foreach($xmlResponse->project as $project) {
 $projects[$project->id_siswa] = $project->nama_siswa;
 echo 'Project ' . $project->nama_siswa . ' has ID ' . $project->id_siswa . PHP_EOL;
}

我收到错误消息：尝试获取非对象的属性？如何解决？

将其直接指向item 属性。

foreach($xmlResponse->data_nilai_siswa->item as $project) {
    $projects[$project->id_siswa] = $project->nama_siswa;
    echo 'Project ' . $project->nama_siswa . ' has ID ' . $project->id_siswa . '<br/>'; 
}
