What are some potential pitfalls of using triggers in PHP MySQL databases?

One potential pitfall of using triggers in PHP MySQL databases is that they can lead to unexpected behavior if not carefully implemented. It is important to thoroughly test triggers before deploying them to ensure they do not cause unintended consequences. Additionally, triggers can make the database harder to maintain and debug if they are overly complex or if there are too many of them. 

// Example of a simple trigger in PHP MySQL that updates a column in a table
// Ensure the trigger is thoroughly tested before deployment to prevent unexpected behavior

$sql = "CREATE TRIGGER update_column_trigger BEFORE UPDATE ON table_name
        FOR EACH ROW
        BEGIN
            SET NEW.column_name = NEW.column_name + 1;
        END";
mysqli_query($conn, $sql);
