Guys, I would like to ask how to compare the answers in the database, but I can't figure it out no matter what I do.

Question

<div class="question-type">一、判断题<span>（共<?=$count_jg?>题，每题<?=$j_score['j_score'] ?>分）</span></div>
    <?php foreach($jg as $k=>$v): ?>
    <div class="question-each">
        <!-- 标题 -->
        <div class="question-name"><?=$v[0]?>. <?=$v['1']?></div>
        <!-- 选项 -->
 <div class="question-option">
 <label><input type="radio" value="true" name="check" required><?=$v[3]?></label>
<label><input type="radio" value="false" name="check" required><?=$v[4]?></label>
        </div>
    </div>
