    for database connection try these codes..

    database.php

       <?php
    try{
        $db = new PDO('mysql:host=localhost;dbname=database_name', "username" , "password");
        $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    }catch(PDOException $e){
        print "error in connection" . $e->getMessage();
    }
    

    now,this php file will access the name of image file stored in database image.php

        <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Document</title>
    </head>
    <body>
        <?php
        require_once 'database.php';
    
        $stmt = $db->query("SELECT image_name FROM tablename");
        $row = $stmt->fetchall(PDO::FETCH_ASSOC);
        foreach ($row as $value) {
            $filename = $value['image_name'];
    
    
    
            ?>
            <a href="download.php?id=<?php echo $filename;?>"><?php echo $filename . "<br>";?></a>
            <?php }?>
        </body>
        </html>
    

    download.php

        <?php 
    
    $filename = $_GET["id"];
    header('Content-Type: image/jpg');
    header('Content-Disposition: attachment; filename="' . basename($filename) . '";');
    readfile ($filename);
    
    exit;
