How to use PHP to implement online voting and questionnaire functions

Introduction:
With the popularity and development of the Internet, online voting and questionnaires have become a A common way to collect user feedback and opinions. As a scripting language widely used in web development, PHP can easily implement online voting and questionnaire functions. This article will introduce how to use PHP to implement these functions and provide corresponding code examples.

1. Implementation of online voting function

Online voting function usually includes the display of questions, selection of options and statistics of results. Below is an example of implementing a simple voting function.

First, create a form for voting questions and PHP code to process the voting results.

HTML code example (vote.html):

<!DOCTYPE html>
<html>
    <head>
        <title>在线投票</title>
    </head>
    <body>
        <form action="vote.php" method="post">
            <p>你最喜欢的编程语言是：</p>
            <input type="radio" name="language" value="PHP"> PHP<br>
            <input type="radio" name="language" value="Python"> Python<br>
            <input type="radio" name="language" value="Java"> Java<br>
            <input type="submit" value="提交">
        </form>
    </body>
</html>

Copy after login

PHP code example (vote.php):

<?php
    // 处理投票结果的逻辑
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        $language = $_POST["language"];
        // 将投票结果保存到数据库或其他存储方式中
        // 这里只简单打印投票结果
        echo "你选择的编程语言是：" . $language;
    }
?>

Copy after login

After the user selects the programming language, click the submit button, The form will be submitted to the vote.php page, and then the PHP code will process the voting results and display them on the page.

2. Implementation of Questionnaire Function

Different from the voting function, questionnaires usually have multiple questions. Each question can have multiple options, and the user needs to select one or more. Below is an example of implementing a simple questionnaire function.

First, create a questionnaire form and PHP code to process the questionnaire results.

HTML code example (survey.html):

<!DOCTYPE html>
<html>
    <head>
        <title>调查问卷</title>
    </head>
    <body>
        <form action="survey.php" method="post">
            <p>问题1：你喜欢的颜色是：</p>
            <input type="checkbox" name="color[]" value="红色"> 红色<br>
            <input type="checkbox" name="color[]" value="蓝色"> 蓝色<br>
            <input type="checkbox" name="color[]" value="绿色"> 绿色<br>
            <p>问题2：你平时喜欢的活动有：</p>
            <input type="checkbox" name="activity[]" value="读书"> 读书<br>
            <input type="checkbox" name="activity[]" value="旅游"> 旅游<br>
            <input type="checkbox" name="activity[]" value="运动"> 运动<br>
            <input type="submit" value="提交">
        </form>
    </body>
</html>

Copy after login

PHP code example (survey.php):

<?php
    // 处理问卷结果的逻辑
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        $color = $_POST["color"];
        $activity = $_POST["activity"];

        // 将问卷结果保存到数据库或其他存储方式中
        // 这里只将结果打印出来
        echo "你喜欢的颜色是：" . implode(", ", $color) . "<br>";
        echo "你平时喜欢的活动有：" . implode(", ", $activity);
    }
?>

Copy after login

After the user selects the questions and options, click the submit button , the form will be submitted to the survey.php page, and then the PHP code will process the survey results and display them on the page.

Conclusion:
By using PHP scripting language, we can implement simple online voting and questionnaire functions. For more complex voting and questionnaire needs, we can combine databases to save questions, options and results, as well as perform more advanced result statistics and analysis. The sample code provided in this article is just a simple demonstration, and readers can modify and expand it according to actual needs. I believe that through learning and practice, you can easily realize the online voting and questionnaire functions you want.
