Question

我正在从数据库中获取Blob数据（pdf），但是执行代码时会显示空白页。也许ahref标记无法正常工作，或者代码存在某些问题或某些语法错误，请指导我是php的新手。

<html>
    <head>
        <title>Download File From MySQL</title>
    </head>
    <body>
        <?php
            $con=mysqli_connect("localhost","root","","mydb");
            $query = "SELECT id, name FROM upload";
            $result = mysqli_query($con,$query) or die('Error, query failed');
            if(mysqli_num_rows($result) == 0) {
                echo "Database is empty <br>";
            } else {
                while(list($id, $name) = mysqli_fetch_array($result)) {
        ?>
                    <a href='download.php?id=<?php=$id;?>'><?php=$name;?></a> <br>
        <?php 
                }
            }
        ?>
    </body>
</html>
