Question

我刚开始使用PHP并做了一些教程。我刚刚构建了以下PHP联系表单，但标题中的PHP语法渗入网页，我完全不确定为什么？值得一提的是，我还将此文件保存为contactForm.php而不是contactForm.html（这有什么不同）。这有什么不对？

<!DOCTYPE html>
<head>
    <meta charset="utf-8">
    <title> Exercise: Contact Form</title>
    <link type="text/css" rel="stylesheet" href="css/myStyle.css" />

    <?php
        $name = $_POST ['name'];
        $email = $_POST ['email'];
        $message = $_POST ['message'];
        $from = 'From: Me';
        $to = 'email@email.co.uk';
        $subject = 'Hello';
        $human = $_POST ['human'];

        $body = "From $name\n Email: $email\n Message: $message\n";

        if ($_POST ['submit'] && $human == '4') {
            if (mail ($to, $subject, $body, $from)) {
                echo '<p>Your message has been sent!</p>';
            }
            else{
                echo '<p>Something went wrong, please try again.</p>';
            }
        }
        else if ($_POST ['submit'] && $human != '4') {
                echo '<p>You answered the anti-spam question incorrectly.</p>';
            }
    ?>
</head>
<body>
    <header>
        <h1>My Test Page</h1>
    </header>

    <form id="testForm" method="post" action="contactForm.php">
        <label>Name:</label>
        <input class="input-fields" type="text" name="name" placeholder="Name" />
        <label>E-mail:</label>
        <input class="input-fields" type="email" name="email" placeholder="Email Address" />
        <label>Message:</label>
        <textarea class="input-fields"  name="message" placeholder="Enter Message here" rows="5"></textarea>
        <label>What is 2 + 2?</label>
        <input class="input-fields" name="human" placeholder="Enter Answer">
        <input type="submit" name="submit" id="submit" value="Click to Submit" />
    </form>
</body>

以下是它如何显示的图像......

PHP必须在具有php引擎的Web服务器上运行。它无法从桌面上的文件直接在浏览器中运行。
