错误/异常

示例

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\Document::fromPHP($rc)->toRelaxedExtendedJSON();

?>

以上示例的输出类似于:

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\Document::fromPHP($rc)->toRelaxedExtendedJSON();

?>

以上示例的输出类似于:

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

{ "level" : "local" }
