MongoDB\Driver\WriteResult::getUpsertedIds — 返回插入的文档的标识符数组
此函数没有参数。
返回一个标识符数组（即 "_id" 字段值），表示插入的文档。数组键将对应于负责插入的写入操作（来自 MongoDB\Driver\BulkWrite）的索引。
示例 #1 MongoDB\Driver\WriteResult::getUpsertedIds() 示例
<?php
$manager = new MongoDB\Driver\Manager;
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$bulk->update(['x' => 1], ['$set' => ['y' => 3]]);
$bulk->update(['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->update(['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);
$bulk->delete(['x' => 1]);
$result = $manager->executeBulkWrite('db.collection', $bulk);
var_dump($result->getUpsertedIds());
?>上面的示例将输出类似于以下内容
array(2) {
[2]=>
object(MongoDB\BSON\ObjectId)#4 (1) {
["oid"]=>
string(24) "580e62a224f2302f191b880b"
}
[3]=>
object(MongoDB\BSON\ObjectId)#5 (1) {
["oid"]=>
string(24) "580e62a224f2302f191b880c"
}
}
