我看到了很多问题，但其中一个问题是您没有正确地逃避php插入


 echo "<td>"."<input type=text name=questionID size=5 value=".$records['question_id']." </td>";



一个主要问题是您试图将原始POST数据设置到数据库中。这是一个巨大的安全漏洞。其他问题，如php的其余部分，与引号、双引号、分号等有关。。。仔细阅读语法。你的整个脚本基本上都错了。
我不熟悉PHP、MYSQL和HTML，我知道我会有很多缺陷。我将阅读更多关于语法的内容，并尽我所知修改我所有的语法缺陷。我正在尝试创建一个测验应用程序，但这一部分阻碍了我。

 echo "<td>"."<input type=text name=questionID size=5 value=".$records['question_id']." </td>";



 echo '<td><input type="text" name="questionID" size="5" value="'.$records['question_id'].'" /></td>';



 $UpdateQuery = "UPDATE $table SET question_description='$_POST[description]', option_a='$_POST[option1]', option_b='$_POST[option2]', option_c='$_POST[option3]', answer='$_POST[dropdown]', question_id='$_POST[questionID]'  WHERE question_id='$_POST[hidden]'";
