(mongodb >=1.2.0)

MongoDB\Driver\WriteConcern::bsonSerialize — Returns an object for BSON serialization

说明

参数

此函数没有参数。

返回值

Returns an object for serializing the WriteConcern as BSON.

错误／异常

示例

示例 #1 MongoDB\Driver\WriteConcern::bsonSerialize() with majority write concern

<?php

$wc = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY);
var_dump($wc->bsonSerialize());

echo "\n", MongoDB\BSON\Document::fromPHP($wc)->toRelaxedExtendedJSON();

?>

以上示例的输出类似于：

object(stdClass)#2 (1) {
  ["w"]=>
  string(8) "majority"
}

{ "w" : "majority" }

示例 #2 MongoDB\Driver\WriteConcern::bsonSerialize() with wtimeout and journal

<?php

$wc = new MongoDB\Driver\WriteConcern(2, 1000, true);
var_dump($wc->bsonSerialize());

echo "\n", MongoDB\BSON\Document::fromPHP($wc)->toRelaxedExtendedJSON();

?>

以上示例的输出类似于：

object(stdClass)#2 (3) {
  ["w"]=>
  int(2)
  ["j"]=>
  bool(true)
  ["wtimeout"]=>
  int(1000)
}

{ "w" : 2, "j" : true, "wtimeout" : 1000 }
