所以下面我有一个数组，我需要从中获取数据，我需要在foreach循环中输出它：

数组输出：

array(2) {

  object(Question)#16 (3) {
    ["answers"]=>
    array(2) {
      [0]=>
      object(Answer)#18 (5) {
        ["id"]=>
        string(3) "144"
        ["answer"]=>
        string(4) "levi"
        ["questionId"]=>
        string(3) "260"

    string(3) "259"
    ["question"]=>
    string(15) "How to make tea"
  }
}

非常感谢帮助

我的开始，但根本不是一个想法：

$questions =  Quiz::OutputQuestions($id);

foreach($questions as $question) {
    echo 'Question: ' . $question['id']['question'];
    echo 'Answers: <br />';

    foreach($answers as $answer) {
          echo '- Answer <br />';
    }
}

Answer 1

您的顶级数组$ questions中似乎有对象而不是数组。所以你可以试试这段代码：

$questions =  Quiz::OutputQuestions($id);

foreach($questions as $question) {
    echo 'Question: ' . $question->question;
    echo 'Answers: <br />';

    foreach($question->answers as $answer) {
          echo '- ' . $answer->answer;
    }
    echo '<br />';
}

数组输出问题及其asnwers
