In this tutorial i am going to store file name, file type, and file size.
import the following sql code in your phpmyadmin. Database crediantials.


CREATE DATABASE `dbtuts` ;
CREATE TABLE `dbtuts`.`tbl_uploads` (
`id` INT( 10 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`file` VARCHAR( 100 ) NOT NULL ,
`type` VARCHAR( 10 ) NOT NULL ,
`size` INT NOT NULL
) ENGINE = MYISAM ;

Database configuration.


$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "dbtuts";
mysql_connect($dbhost,$dbuser,$dbpass) or die('cannot connect to the server'); 
mysql_select_db($dbname) or die('database selection problem');

The HTML Form.

index.php


<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>File Upload and view With PHP and MySql</title>
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="file" />
<button type="submit" name="btn-upload">upload</button>
</form>
</body>
</html>

above html form sends the data to the following PHP script and joining this html and php script you can easily upload files to the database .
upload.php


<?php
if(isset($_POST['btn-upload']))
{    
     
 $file = rand(1000,100000)."-".$_FILES['file']['name'];
    $file_loc = $_FILES['file']['tmp_name'];
 $file_size = $_FILES['file']['size'];
 $file_type = $_FILES['file']['type'];
 $folder="uploads/";
 
 move_uploaded_file($file_loc,$folder.$file);
 $sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$file','$file_type','$file_size')";
 mysql_query($sql); 
}
?>

Display files from MySql.

Now we are going to fetch uploaded files from MySql Database, data selecting from mysql database i hope you know that…
view.php


<table width="80%" border="1">
    <tr>
    <td>File Name</td>
    <td>File Type</td>
    <td>File Size(KB)</td>
    <td>View</td>
    </tr>
    <?php
 $sql="SELECT * FROM tbl_uploads";
 $result_set=mysql_query($sql);
 while($row=mysql_fetch_array($result_set))
 {
  ?>
        <tr>
        <td><?php echo $row['file'] ?></td>
        <td><?php echo $row['type'] ?></td>
        <td><?php echo $row['size'] ?></td>
        <td><a href="uploads/<?php echo $row['file'] ?>" target="_blank">view file</a></td>
        </tr>
        <?php
 }
 ?>
</table>

that’s it

Complete script.

dbconfig.php


?<php
$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "dbtuts";
mysql_connect($dbhost,$dbuser,$dbpass) or die('cannot connect to the server'); 
mysql_select_db($dbname) or die('database selection problem');
?>

include_once 'dbconfig.php';
if(isset($_POST['btn-upload']))
{    
     
 $file = rand(1000,100000)."-".$_FILES['file']['name'];
    $file_loc = $_FILES['file']['tmp_name'];
 $file_size = $_FILES['file']['size'];
 $file_type = $_FILES['file']['type'];
 $folder="uploads/";
 
 // new file size in KB
 $new_size = $file_size/1024;  
 // new file size in KB
 
 // make file name in lower case
 $new_file_name = strtolower($file);
 // make file name in lower case
 
 $final_file=str_replace(' ','-',$new_file_name);
 
 if(move_uploaded_file($file_loc,$folder.$final_file))
 {
  $sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$final_file','$file_type','$new_size')";
  mysql_query($sql);
  ?>
  <script>
  alert('successfully uploaded');
        window.location.href='index.php?success';
        </script>
  <?php
 }
 else

  <script>
  alert('error while uploading file');
