Php-calling multiple interfaces for database changes-transaction processing

PHP Transaction Database

What I do is the encapsulation of the PHP upper interface. The bottom interface of others is to do a single increase and deletion. I need to call the interfaces on several different servers to handle the data I need. Update to the appropriate interface. However, if some data changes are unsuccessful. A rollback of the transaction is required. Now I know the same database, the operation of the database transaction is possible. But different server different database, I need transaction processing words. What to do. I Baidu a distributed transaction. But I didn't read it. Baidu is talking about Java. I don't write PHP as much as he does. Ask the great God for guidance
