执行变量的操作然后保存，并使用它们到另一个位置

Question

我有两个 PHP 页面，名为 index.php 和 result.php。我想在 index.php 页面中执行一些操作并为这些变量保留一些值。然后我想将它们传递到 result.php 页面。

我会在表单中使用 action="result.php" 还是使用 header('location: result.php') 传递它们？

如果你建议 header() 那么我会把 header() 代码放在哪里？

我搜索过，但没有得到任何具体结果。

两 php 页

result.php 页

<?php 
    if (isset($_POST['form1'])) {
        $right_ans = $_POST[$right_ans_count];
        $wrong_ans = $_POST[$wrong_ans_count];
        $not_answered = $_POST[$unanswered];
        echo "Right Answer: ". $right_ans;
        echo "Wrong Answer: ". $wrong_ans;
        echo "Not Answered: ". $not_answered;
    }
?>

index.php 页

    <?php
    ob_start();
?>

<?php

    if(isset($_REQUEST['form1'])) {
        $success_message = "<div class='success'>Congratulations! Your answer is right.</div>";
        $error_message = "<div class='error'>Sorry! Your answer is wrong.</div>";
        $right_ans_count = 0;
        $wrong_ans_count = 0;
        $unanswered = 0;
        $answer1 = $_POST['question1'];
        $answer2 = $_POST['question2'];
        $answer3 = $_POST['question3'];
        $answer4 = $_POST['question4'];
    }

?>

Answer 1

您 html 中的简单解决方案使用表单操作

<form action="/result.php" method="post">

所以当您提交表单时，您将在我们的 result.php 文件中获得所有 post 值 result.php

<?php 
if (isset($_POST['form1'])) {
$answer1 = $_POST['question1'];
$answer2 = $_POST['question2'];
$answer3 = $_POST['question3'];
$answer4 = $_POST['question4'];
if($answer1=="Bangladesh") {
  echo $success_message;
  $right_ans_count++;
}
  else if($answer1=="") {
  $unanswered++;
}
else {
  echo $error_message;
  $wrong_ans_count++;
}
..
.. 
}
?>

在您的 result.php 文件中，您可以检查他们的答案是否正确。
