將是幫助

我開始感激，但不會不惜一切只是一個想法工作：

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

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

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

Answer 1

看來你有對象和而不是頂級數組$ question中的數組。所以你可以試試這個代碼：

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

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

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