PHP display image BLOB from MySQL
PhpMysqlPhp Problem Overview
I'm attempting to display an image stored in the BLOB column in the database;
I fetch the data from the database with a SELECT perform no transformations on the data and display it with the following (from a script whose only output is the following):
header("Content-Type: image/jpeg");
echo $image;
Please note chrome is displaying the content size as the correct size for the image as well as the correct mime type (image/jpeg
). nothing is echoing out before the header and ive checked the blob in the database is correct. There is also no trailing whitespace before or after the <?php ?>
tags.
chrome/IE displays an image icon but not the image itself. any ideas?
EDIT: image is got the from the database as such:
$sql = "SELECT * FROM products WHERE id = $id";
$sth = $db->query($sql);
$row = $sth->fetch();
$image = $row['image'];
var_dump($image) gives:
string 'ÿØÿà�JFIF��x�x��ÿá�ZExif��MM�*�����������J��������Q�������Q������tQ������t�����† ��±ÿÛ�C�

Php Solutions
Solution 1 - Php
Try it like this.
For inserting into DB
$db = new mysqli("localhost", "root", "", "DbName");
$image = file_get_contents($_FILES['images']['tmp_name']);
$query = "INSERT INTO products (image) VALUES(?)";
$stmt = $db->prepare($query);
$stmt->bind_param('s', $image);
$stmt->execute();
For accessing image from Blob
$db = new mysqli("localhost", "root", "", "DbName");
$sql = "SELECT * FROM products WHERE id = ?";
$stmt = $db->prepare($sql);
$stmt->bind_param('s', $id);
$stmt->execute();
$result = $stmt->get_result();
$row = $result->fetch_array();
echo '<img src="data:image/jpeg;base64,'.base64_encode($row['image']).'"/>';
Solution 2 - Php
This is what I use to display images from blob:
echo '<img src="data:image/jpeg;base64,'.base64_encode($image->load()) .'" />';
