Php If/else带有一个回波区域

所以我有点困惑。我不太确定我应该如何去做if/else语句，在顶部有回音，有答案，有子弹

 <?php
    echo 
    ?>
    </p>
<p>
  A Chicken
  <input type="radio" name="radio" id="radio3" value="no">
  <label for="radio3">Choose this answer</label>
</p>
<p dir="ltr">A Ear of Corn.
  <input type="radio" name="radio" id="radio2" value="no">
          <label for="radio2">Choose this answer</label>
</p>
        <p dir="ltr"> A Heart. 
          <input type="radio" name="radio" id="radio" value="yes"> Choose this answer
        </p>


 <p dir="ltr">
          <input type="button" name="button28" id="button28" value="Yes! That is the answer I chose!">

你可以用很多方法来做到这一点。下面是一个小示例，帮助您开始使用表单

<?php

    $answer = '';

    if(isset($_POST['send'])            //check if the form has been sent
       && isset($_POST['answer'])){     //check if an answer is filled in


        //You could also use a switch -> http://php.net/manual/en/control-structures.switch.php
        if($_POST['answer'] == 'chicken'){      //check if post variable answer value = chicken

            $answer = 'your answer is "a chicken"';

        }elseif($_POST['answer'] == 'corn'){    //check if post variable answer value= corn

            $answer = 'your answer is "A Ear of Corn."';

        }elseif($_POST['answer'] == 'heart'){   //check if post variable answer value = heart

            $answer = 'your answer is "A Heart"';

        }

        //echo the variable.
        echo $answer;

    }

?>


<form method="POST" action="">
    <p> A Chicken
        <input type="radio" name="answer" id="radio3" value="chicken">
        <label for="radio3">Choose this answer</label>
    </p>
    <p dir="ltr">A Ear of Corn.
        <input type="radio" name="answer" id="radio2" value="corn">
        <label for="radio2">Choose this answer</label>
    </p>
    <p dir="ltr">A Heart.
        <input type="radio" name="answer" id="radio" value="heart">Choose this answer
    </p>

    <input type="submit" name="send" id="button28" value="Yes! That is the answer I chose!">

</form>

如果您的问题基本上是关于如何基于If/else子句输出某些HTML代码，那么使用您发布的大量HTML代码，使用HEREDOCS签出PHP手册会更好

祝你好运

那么，您的问题是什么呢？当您使用？>显示文本HTML时，不使用echo。要么删除echo，要么使用here-doc。如果需要，您想把它放在哪里？
