我尝试从用户处拍摄图像并显示它。但不知何故它没有在浏览器上显示。我现在正在使用safari。

    function displayThanks() {
        ?>
        <h1>Thank You</h1>
        <p>Thanks for uploading your photo<?php if ( $_POST["visitorName"] )echo ", " . $_POST["visitorName"] ?>!</p>
        <p>Here's your photo:</p>
        <p><img src="/Library/WebServer/Documents/image/<?php echo $_FILES['photo']['name'] ?>" alt="Photo" width="20em" height="30em"/></p>
        <?php
    }
    ?>
</body>
</html>

代码工作正常，但是当我在浏览器上运行时，它会将输入图像保存到目录中，但不会在页面上显示。它显示了一个＆＃39;？＆＃39;马克。

我尝试了所有方法，但无法弄清楚什么是错误的。
