How to Retrieve and Display Images from a Database using PHP
Displaying images from a database can be a crucial task for web development. This article addresses a common issue users encounter when attempting to display database-stored images, focusing on a specific issue where the image is displayed as a filename instead of the actual image data.
To resolve this issue, it's essential to use the proper methods for retrieving and displaying binary data, such as images, from a database. Traditional methods that simply echo or print the image data will not work correctly.
The provided solution demonstrates a more effective approach using PHP's mysqli library, which allows you to establish a connection to your database, execute SQL queries, and retrieve the binary data for the image.
Here's an example of how to implement this solution:
<?php // Establish a connection to your database $db = mysqli_connect("localhost", "root", "", "databaseName"); // Prepare and execute an SQL query to retrieve the image data $sql = "SELECT * FROM table_name WHERE id = $id"; $result = mysqli_query($db, $sql); // Fetch the result and extract the image data $row = mysqli_fetch_array($result); $imageData = $row['image']; // Encode the image data to display it as an image echo '<img src="data:image/jpeg;base64,'.base64_encode($imageData).'">'; ?>
By using this approach, you can effectively retrieve and display images stored in a database within your PHP application.
