MongoDB\Driver\BulkWriteCommandResult::getModifiedCount — Returns the number of existing documents updated
If the update operation results in no change to the document (e.g. setting the value of a field to its current value), the modified count may be less than the value returned by MongoDB\Driver\BulkWriteCommandResult::getMatchedCount().
This function has no parameters.
Returns the total number of existing documents updated by all operations.

$bulk = new MongoDB\Driver\BulkWriteCommand;
$bulk->insertOne('db.coll', ['x' => 1]);
$bulk->updateOne('db.coll', ['x' => 1], ['$set' => ['y' => 3]]);
$bulk->updateOne('db.coll', ['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->updateOne('db.coll', ['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);
$bulk->deleteMany('db.coll', []);
$result = $manager->executeBulkWriteCommand($bulk);
var_dump($result->getModifiedCount());
?>The above example will output:
int(1)
