In PHP, what methods can be used to dynamically output images based on user permissions set in a database?

To dynamically output images based on user permissions set in a database, you can create a PHP script that retrieves the user's permissions from the database and then conditionally displays the image based on those permissions. One way to achieve this is by using a combination of PHP code to query the database and HTML to output the image. 

<?php
// Assuming you have a database connection established

// Query the database to get the user's permissions
$user_id = $_SESSION['user_id']; // Assuming user ID is stored in session
$query = "SELECT image_path FROM images WHERE user_id = $user_id";
$result = mysqli_query($conn, $query);

// Check if the user has permission to view the image
if(mysqli_num_rows($result) > 0) {
    $row = mysqli_fetch_assoc($result);
    $image_path = $row['image_path'];
    echo "<img src='$image_path' alt='User Image'>";
} else {
    echo "You do not have permission to view this image.";
}
?>
