Database Structure:
 Database Name: test

 CREATE TABLE IF NOT EXISTS `pdf` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(100) NOT NULL,
  `size` varchar(100) NOT NULL,
  `type` varchar(10) NOT NULL,
  PRIMARY KEY(id)
) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=latin1;
 

Now copy The Below Codes for Certain File.
connect.php:
<?php
// Creating connection test is our database name
$conn = new mysqli('localhost', 'root', '','test');
// Checking connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
?>
 
index.php:
Create Index.php to Display Uploaded File with Download Link.
<?php
include("connect.php");
include('upload.php');
?>
<hr/>
<link rel="stylesheet" href="style.css" type="text/css"/>
<table>
 <tr>
   <th>Book Name</th>
   <th>Size</th>
   <th>Type</th>
   <th>Action</th>
  </tr>
 <?php
 $result=mysqli_query($conn,"SELECT*FROM pdf ORDER by ID DESC");
 while($row=$result->fetch_array()){
  ?>
 
  <tr>
  <td><?php echo $row['name'];?></td>
  <td><?php echo number_format($row['size']/(1024*1024),2);?>MB</td>
  <td><?php echo $row['type'];?></td>
  <td><a href="download.php?pdf=<?php echo $row['name'];?>">Download</a></td>
  </tr>
  <?php }?>
  </table>
upload.php:
Create Upload.php file to Display Upload form and Processing Upload Selected File.
Add the below HTML codes top of the upload.php file to Display Upload form.
<h2>Upload,Save and Download PDF File Using PHP MySQL</h2>
<form method="POST" action="" enctype="multipart/form-data">
<input type="file" name="pdf"/>
<input type="submit" name="submit" value="Upload"/>
</form>
<?php
include("connect.php");
$errors=1;
 //Targeting Folder
 $target="files/";
 
if(isset($_POST['submit'])){
 $target=$target.basename($_FILES['pdf']['name']);
 //Getting Selected PDF Type
 $type=pathinfo($target,PATHINFO_EXTENSION);
 //Allow Certain File Format To Upload
 if($type!='pdf' && $type!='doc' && $type!='docx' && $type!='epub' ){
  echo "Only PDF,DOC,DOCX,Epub files format are allowed to Upload";
  $errors=0;
 }
 //Checking for File Size 1000000 bytes== 1MB
  $filesize=$_FILES['pdf']['size'];
if ($filesize < 100 && $filesize< 2000000){
   echo 'You Can not Upload Large File(2MB) by Default ini setting..<a href="http://www.codenair.com/2018/03/how-to-upload-large-file-in-php.html">How to upload large file in php</a>'; 
    $errors=0;
   }
  //checking for Exsisting Doc File Files
  if(file_exists($target)){
   echo "File Already Exist";
   $errors=0;
  }
 // Check if $errors is set to 0 by an error
 if($errors==0){
  echo 'Your File Not Uploaded';
 }else{
  //if not error encountered 
   //Moving The PDF or Doc file to Desired Directory
  $uplaod_success=move_uploaded_file($_FILES['pdf']['tmp_name'],$target);
  if($uplaod_success==TRUE){
   //Getting Selected PDF Information
   $name=$_FILES['pdf']['name'];
   $size=$_FILES['pdf']['size'];
   $result=mysqli_query($conn,"INSERT INTO pdf (name,size,type)VALUES('$name','$size','$type')");
   if($result==TRUE){
    echo "Your pdf '$name' Successfully Upload and Information Saved Our Database";
   }
 }
}
}
?>

download.php
In this step we order to the browser to download file forcefully..
<?php
if(isset($_GET['pdf']))
{
    $var_1 = $_GET['pdf'];
$dir = "files/"; // trailing slash is important
$file = $dir . $var_1;

if (file_exists($file))
    {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    exit;
    }
}
?>

table th, td{
   border: 1px solid green;
   text-align:left;
}
th,td{
 padding:8px;
  
}
table{
