In the context of PHP, what best practices should be followed when updating sort order values in a database table?

When updating sort order values in a database table in PHP, it is important to ensure that the values are unique and sequential to maintain the desired order. One common approach is to reassign sort order values based on the desired order, either by incrementing or decrementing the values as needed. Additionally, it is recommended to use prepared statements to prevent SQL injection attacks and to handle errors gracefully. 

// Assuming $newSortOrderValues is an array containing the new sort order values
// Assuming $connection is a PDO database connection

try {
    $connection->beginTransaction();
    
    foreach ($newSortOrderValues as $id => $sortOrder) {
        $query = "UPDATE table_name SET sort_order = :sortOrder WHERE id = :id";
        $statement = $connection->prepare($query);
        $statement->execute(['sortOrder' => $sortOrder, 'id' => $id]);
    }
    
    $connection->commit();
    echo "Sort order values updated successfully!";
} catch (PDOException $e) {
    $connection->rollBack();
    echo "Error updating sort order values: " . $e->getMessage();
}
