What are best practices for integrating user-specific image galleries into PHP-based websites, such as displaying only the images of the logged-in user?

To display only the images of the logged-in user in a PHP-based website, you can achieve this by storing the user's images in a database table with a column for the user ID. When a user logs in, you can query the database to fetch and display only the images associated with that user ID.

// Assuming you have a database connection established

// Get the user ID of the logged-in user
$user_id = $_SESSION['user_id'];

// Query the database to fetch images of the logged-in user
$query = "SELECT * FROM images WHERE user_id = $user_id";
$result = mysqli_query($conn, $query);

// Display the images
while($row = mysqli_fetch_assoc($result)) {
    echo '<img src="' . $row['image_path'] . '" alt="' . $row['image_alt_text'] . '">';
}
