错误/异常

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" }
