MongoDB\Driver\BulkWriteCommandResult::getInsertResults — Returns verbose results for successful inserts
   Since _id fields for inserted documents are generated by
   the extension, the value of insertedId in each result
   will match the return value of
   MongoDB\Driver\BulkWriteCommand::insertOne() for
   the corresponding insert operation.
  
此函数没有参数。
   Returns a document containing the result of each successful insert
   operation, or null if verbose results were not requested. The document
   keys will correspond to the index of the write operation from
   MongoDB\Driver\BulkWriteCommand.
  
示例 #1 MongoDB\Driver\BulkWriteCommandResult::getInsertResults() example
<?php
$manager = new MongoDB\Driver\Manager;
$bulk = new MongoDB\Driver\BulkWriteCommand(['verboseResults' => true]);
$generatedId = $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($generatedId);
var_dump($result->getInsertResults()->toPHP());
?>以上示例的输出类似于:
object(MongoDB\BSON\ObjectId)#3 (1) {
  ["oid"]=>
  string(24) "67f7ee69783dcce702097b41"
}
object(stdClass)#8 (1) {
  ["0"]=>
  object(stdClass)#7 (1) {
    ["insertedId"]=>
    object(MongoDB\BSON\ObjectId)#6 (1) {
      ["oid"]=>
      string(24) "67f7ee69783dcce702097b41"
    }
  }
}
