使用php下载文件,文件存储在文件夹中,文件名存储在数据库中

I am trying to download a file from mysqli database using php for that i have stored file in a folder and file name is stored in the mysqli database.

here is my code...

 $query= mysqli_query($dbo,"SELECT * FROM diff_questions WHERE email = ' $email ' and status= '0' ");
$rows=mysqli_fetch_array($query);
$file=$rows['file'];
$path='http://localhost/admin1/uploads';
?>

echo "<a href='download.php?file=".$file."&path=".$path." '>Download File</a> ";

and now download.php-

<?php
$file = $_GET["file"];
$path = $_GET["path"];
$fullfile = $path.$file;
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=" . Urlencode($file));   
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Description: File Transfer");            
header("Content-Length: " . Filesize($fullfile));
flush();
$fp = fopen($fullfile, "r");
while (!feof($fp))
{
    echo fread($fp, 65536);
    flush();
} 
fclose($fp);
?>

    Once replace your download.php with following code and check if its working for you or not :

    if(isset($_GET["file"])){
          $file = $_GET["file"];
          $path = $_GET["path"];
          $fullfile = $path.$file;
    
          header("Content-Type: application/octet-stream");
          header("Content-Disposition: attachment; filename=" . Urlencode($file));   
          header("Content-Type: application/force-download");
          header("Content-Type: application/octet-stream");
          header("Content-Type: application/download");
          header("Content-Description: File Transfer");            
          $fp = fopen($fullfile,'r');
            while ($line = fgets($fp)) {
            echo($line);
          }
          fclose($fp);
        }
