Using autocommit mode in MySQL can significantly affect how your transactions are managed. Here are some best practices to consider:

Understand Autocommit Behavior: Know that when autocommit is enabled, each SQL statement is treated as a transaction and automatically committed upon success.
Use explicit transactions: Turn off autocommit when executing multiple statements that should be treated as a single transaction for consistency.
Handle errors gracefully: When autocommit is disabled, be sure to handle errors properly to avoid leaving your database in an inconsistent state.
Monitor performance: Carefully evaluate the impact of autocommit mode on the performance of your application to ensure optimal database operations.

Here's an example of how to control autocommit mode in PHP using PDO:


        <?php
            // Create a new PDO connection
            $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'username', 'password');

            // Disable autocommit
            $pdo->setAttribute(PDO::ATTR_AUTOCOMMIT, 0);

            try {
                // Begin transaction
                $pdo->beginTransaction();

                // Execute multiple queries
                $pdo->exec("INSERT INTO users (username) VALUES ('john_doe')");
                $pdo->exec("INSERT INTO users (username) VALUES ('jane_doe')");

                // Commit transaction
                $pdo->commit();
            } catch (Exception $e) {
                // Rollback transaction on error
                $pdo->rollBack();
                echo "Failed: " . $e->getMessage();
            }
        ?>
