Question

对了，我真的开始失去对这件事的诱惑力了。为什么，每当我使用 Google 发布的代码来启用他们的 Google Captcha 文档时，尽管从 HTML 转换为 PHP 文档并遵循所有内容，但我只会在网页上显示原始代码？

这是一个 HTML 文档，文件已更改为 php 扩展名，文档中仍有 HTML 代码，但 php 代码位于 body 标签中。

<!doctype html>
<html>
<head>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<!---HTML CODE HERE--->
<?php
// Checks if form has been submitted
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    function post_captcha($user_response) {
        $fields_string = '';
        $fields = array(
            'secret' => '_______________PRIVATE_KEY_______________',
            'response' => $user_response
        );
        foreach($fields as $key=>$value)
        $fields_string .= $key . '=' . $value . '&';
        $fields_string = rtrim($fields_string, '&');

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
        curl_setopt($ch, CURLOPT_POST, count($fields));
        curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);

        $result = curl_exec($ch);
        curl_close($ch);

        return json_decode($result, true);
    }

    // Call the function post_captcha
    $res = post_captcha($_POST['g-recaptcha-response']);

    if (!$res['success']) {
        // What happens when the CAPTCHA wasn't checked
        echo '<p>Please go back and make sure you check the security CAPTCHA box.</p><br>';
    } else {
        // If CAPTCHA is successfully completed...

        // Paste mail function or whatever else you want to happen here!
        echo '<br><p>CAPTCHA was completed successfully!</p><br>';
    }
} else { ?>
    
<!-- FORM GOES HERE -->
<form method="POST" action="/scripts/mail_html.php" enctype="multipart/form-data">
                <input type="email" name="email" required placeholder="Enter your email"/>
        <div class="g-recaptcha" data-sitekey="_______________PUBLIC_KEY_______________"></div><br/><br/>

</form>

<?php 
} ?>

</body>
</html>

如您所见，您可以清楚地看到编码，而不仅仅是形式。

为什么？
