What are some best practices for tracking and monitoring changes in database tables using PHP?

Tracking and monitoring changes in database tables is essential for maintaining data integrity and security. One common approach is to create a separate table to log all changes, including the user who made the change, the timestamp, and the specific operation performed. By implementing triggers in the database, we can automatically populate this log table whenever a change is made to the main table. 

// Create a log table to track changes
CREATE TABLE log_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    table_name VARCHAR(255),
    operation VARCHAR(50),
    user_id INT,
    timestamp TIMESTAMP
);

// Create a trigger to log changes in the main table
CREATE TRIGGER track_changes
AFTER INSERT ON main_table
FOR EACH ROW
BEGIN
    INSERT INTO log_table (table_name, operation, user_id, timestamp)
    VALUES ('main_table', 'INSERT', NEW.user_id, NOW());
END;

// Repeat the above trigger for UPDATE and DELETE operations
