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

说明

final public MongoDB\Driver\ReadConcern::bsonSerialize ( void ) : object

参数

此函数没有参数。

Returns an object for serializing the ReadConcern as BSON.

错误／异常

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

范例

Example #1 MongoDB\Driver\ReadConcern::bsonSerialize() with empty read concern


<?php

$rc = new MongoDB\Driver\ReadConcern;
var_dump($rc->bsonSerialize());

echo "\n", MongoDB\BSON\toJSON(MongoDB\BSON\fromPHP($rc));

?>

以上例程的输出类似于：

object(stdClass)#2 (0) {
}

{ }

Example #2 MongoDB\Driver\ReadConcern::bsonSerialize() with local read concern


<?php

$rc = new MongoDB\Driver\ReadConcern(MongoDB\Driver\ReadConcern::LOCAL);
var_dump($rc->bsonSerialize());

echo "\n", MongoDB\BSON\toJSON(MongoDB\BSON\fromPHP($rc));

?>

以上例程的输出类似于：

object(stdClass)#2 (1) {
  ["level"]=>
  string(5) "local"
}

{ "level" : "local" }
