Displaying Images from Database Using PHP
In PHP, displaying images stored in a database is a common task. Let's explore a code snippet to accomplish this:
$db = mysqli_connect("localhost","root","","DbName"); $sql = "SELECT * FROM products WHERE id = $id"; $sth = $db->query($sql); $result = mysqli_fetch_array($sth); echo '<img src="data:image/jpeg;base64,'.base64_encode(%20%24result%5B'image'%5D%20).'" alt="How to Display Images from a Database Using PHP?" >';
This code utilizes the MySQL database extension (mysqli) to retrieve image data from a database and then employs base64 encoding to display the image as an inline HTML element. Here's what each section of the code does:
- Database Connection: First, a connection to the database is established using the mysqli_connect function.
- SQL Query: An SQL query is executed to fetch the image data from the products table based on a given id.
- Data Retrieval: The image data is retrieved from the query result.
- Image Encoding: The image data is converted to a base64 string using base64_encode.
- Image Display: A HTML
element is generated to display the image using the base64 encoded data as the source.
By implementing the provided code, you can successfully display images stored in a database on your web page.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
