MongoDB\Driver\ReadConcern::bsonSerialize — Returns an object for BSON serialization
此函數沒(méi)有參數。
Returns an object for serializing the ReadConcern as BSON.
示例 #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));
?>
以上例程的輸出類(lèi)似于：
object(stdClass)#2 (0) {
}
{ }
示例 #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));
?>
以上例程的輸出類(lèi)似于：
object(stdClass)#2 (1) {
["level"]=>
string(5) "local"
}
{ "level" : "local" }
