MongoDB\Driver\Session::startTransactionStarts a transaction

Descripción

final public MongoDB\Driver\Session::startTransaction(array $options = ?): void

Starts a multi-document transaction associated with the session. At any given time, you can have at most one open transaction for a session. After starting a transaction, the session object must be passed to each operation via the "session" option (e.g. MongoDB\Driver\Manager::executeBulkWrite()) in order to associate that operation with the transaction.

Transactions can be committed through MongoDB\Driver\Session::commitTransaction(), and aborted with MongoDB\Driver\Session::abortTransaction(). Transactions are also automatically aborted when the session is closed from garbage collection or by explicitly calling MongoDB\Driver\Session::endSession().
