php中的多个迭代器

I have the following code. Basically, for each question if the answer's "question_id" matches the question's id I need it to list all of the possible answers for the question. It does this for the first question, but then exits the loop.

            <?php foreach ($questions as $question) : ?>
            <tr>
                <td><?php echo $question['question']; ?></td>
                <td><?php echo $question['id']; ?></td>
            </tr>
                <?php foreach ($answers as $answer) : ?>
                <?php if ($answer['question_id'] == $question['id']) { ?>
                <tr>
                    <td>&nbsp;&nbsp;&nbsp;<?php echo $answer['answer']; ?></td>
                </tr>
                <?php } ?>
                <?php endforeach ?>
            <?php endforeach; ?>
            </tr>

How can I continue to iterate through the rest of the $question['id'] values?

    That's basically because you are missing the closing semicolon

    <?php endforeach ?> // <-- here
    

    That should give you a fatal error if you properly setup the error reporting.
