• PHP display image BLOB from MySQL [duplicate] 3 answers

I've uploaded an image and text directly to my table through phpMyAdmin. However when it comes to displaying, the images are showing up as junk text. What could be the issue? The image is a relatively small jpg file. Here is the code:

<?php
    require_once 'login.php';
    $conn = new mysqli($hn, $un, $pw, $db);
    if($conn->connect_error) die($conn->connect_error);
    $query = "SELECT * from classics";
    $result = $conn->query($query);
    if(!$result) die($conn->error);

    $rows = $result->num_rows;

    for($j=0; $j < $rows; $j++) {
         $result->data_seek($j);
         $row=$result->fetch_array(MYSQLI_ASSOC);
         echo 'Cover:' .$row['sleeve'] .'<br>'; 
    }

    $result->close();
    $conn->close();
?>

</div>

Answer 1

Something like this as your echo statement "should" work with your current implementation.

//echo 'Cover:' .$row['sleeve'] .'<br>'; 
echo '<img src="data:image/jpeg;base64,'.base64_encode( $row['sleeve'] ).'"/>';

However @Noor is correct, storing images like this is not very efficient.
