begin_transaction(); // SQL queries $db->query("INSERT INTO table1 (id, name) VALUES (1, 'John')"); $db->query("INSERT INTO table2 (id, age) VALUES (1, 30)"); // Commit transaction $db->commit(); ?>
begin_transaction(); // SQL queries $db->query("INSERT INTO table1 (id, name) VALUES (1, 'John')"); $db->query("INSERT INTO table2 (id, age) VALUES (1, 30)"); // Rollback transaction $db->rollback(); ?>In this example, we begin a transaction using `$db->begin_transaction()`. Then we execute two SQL queries to insert data into two different tables. If any of the queries fail, we use `$db->rollback()` to roll back the entire transaction. PHP DB start_transaction is a part of the PHP database abstraction layer called PHP DB. It is an open-source library that provides a unified API for accessing various database systems.
