MongoDB\Driver\Session::startTransaction — Starts a transaction
$options
] ) : voidStarts 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().
optionsOptions can be passed as argument to this method. Each element in this options array overrides the corresponding option from the "defaultTransactionOptions" option, if set when starting the session with MongoDB\Driver\Manager::startSession().
