How can PHP be used to dynamically update the sorting order of images in a database based on user input?

To dynamically update the sorting order of images in a database based on user input, you can create a form where users can select the sorting criteria (e.g. by name, date, size) and then use PHP to update the database query accordingly. You can use SQL queries to retrieve the images from the database based on the selected sorting criteria and display them in the desired order. 

// Assuming you have a form with a select input for sorting criteria
$sort_by = $_POST['sort_by']; // Get the selected sorting criteria from the form

// Construct the SQL query based on the selected sorting criteria
$sql = "SELECT * FROM images ORDER BY $sort_by";

// Execute the query and display the images in the desired order
$result = mysqli_query($connection, $sql);
while($row = mysqli_fetch_assoc($result)) {
    echo '<img src="' . $row['image_url'] . '" alt="' . $row['image_alt'] . '">';
}
