How can SQL triggers be utilized to maintain a continuous ranking order when entries are added, removed, or updated in a PHP MySQL database?

To maintain a continuous ranking order in a PHP MySQL database when entries are added, removed, or updated, SQL triggers can be utilized. By creating triggers on the table that automatically update the ranking order when changes are made, the ranking will always stay up to date without manual intervention.

CREATE TRIGGER update_ranking
AFTER INSERT ON table_name
FOR EACH ROW
BEGIN
    SET @rank = 0;
    UPDATE table_name 
    SET ranking = (@rank := @rank + 1)
    ORDER BY column_to_rank;
END;
