How Can I Display BLOB Images from a MySQL Database on My PHP Page?

Retrieving BLOB Image from MySQL Database for PHP Page Display

Encountering difficulties in displaying BLOB images from a MySQL database on a PHP page? This article addresses the issue and provides viable solutions to overcome the dreaded binary JPEG data nightmare.

Defining the Issue:

You seek to incorporate an image into your "Details" page, retrieving it from a BLOB column in the MySQL database. However, despite your efforts, only incomprehensible binary data adorns your page, leaving you scratching your head.

Resolving the Conundrum:

Option 1: Inline Base64 Encoding

For smaller images, you can resort to inline base64 encoding. This method converts the image binary data into a string that can be directly embedded in the HTML. Here's the code snippet for this approach:

echo '<dt><strong>Technician Image:</strong></dt><dd>'
     . '<img src="data:image/jpeg;base64,' . base64_encode($row2['image']) . '" width="290" height="290">'
     . '</dd>';

Option 2: Dedicated Image Retrieval Page

This option is preferable for numerous images. Create a separate PHP page (e.g., "image.php") responsible for retrieving and outputting the image based on a query-string parameter:

HTML:

<img src="image.php?id=<?php echo $image_id; ?>" />

PHP File (image.php):

<?php
$id = (isset($_GET['id']) &amp;&amp; is_numeric($_GET['id'])) ? intval($_GET['id']) : 0;
$image = getImageFromDatabase($id); // your code to fetch the image

header('Content-Type: image/jpeg');
echo $image;
?>

Remember to specify the MIME type ("image/jpeg") for the header in this method.

By implementing either of these methods, you can now proudly display your images from the MySQL database, showcasing your technicians' mugs or any other visually appealing data you may possess. Bon voyage in your web development endeavors!
