从PHP中的std类对象和数组中获取值

Question

我正在尝试使用PHP从这种类型的数组中获取值。如何从这个数组中访问主题名称。我可以在不使用2 foreach的情况下获得这些值吗？ 注意：主题数组计数不固定

 stdClass Object
(
    [Examination] => Array
        (
            [0] => stdClass Object

Answer 1

你需要嵌套的foreach

foreach($data->Examination as $row)
{
    foreach($row->ExamSubjects->ExamSubject as $row1)
    {
        echo $row1->SubjectName

    }

 }
