バージョン 説明
PECL mongodb 1.4.0 The third parameter is now an options array. For backwards compatibility, this paramater will still accept a MongoDB\Driver\ReadPreference object.

例1 MongoDB\Driver\Manager::executeQuery() example

<?php

$manager 
= new MongoDB\Driver\Manager("mongodb://localhost:27017");

$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1]);
$bulk->insert(['x' => 2]);
$bulk->insert(['x' => 3]);
$manager->executeBulkWrite('db.collection'$bulk);

$filter = ['x' => ['$gt' => 1]];
$options = [
    
'projection' => ['_id' => 0],
    
'sort' => ['x' => -1],
];

$query = new MongoDB\Driver\Query($filter$options);
$cursor $manager->executeQuery('db.collection'$query);

foreach (
$cursor as $document) {
    
var_dump($document);
}

?>

上の例の出力は以下となります。

object(stdClass)#6 (1) {
  ["x"]=>
  int(3)
}
object(stdClass)#7 (1) {
  ["x"]=>
  int(2)
}

例2 Limiting execution time for a query

The "maxTimeMS" MongoDB\Driver\Query option may be used to limit the execution time of a query. Note that this time limit is enforced on the server side and does not take network latency into account. See » Terminate Running Operations in the MongoDB manual for more information.

<?php

$manager 
= new MongoDB\Driver\Manager('mongodb://localhost:27017');

$filter = ['x' => ['$gt' => 1]];
$options = [
    
'maxTimeMS' => 1000,
];

$query = new MongoDB\Driver\Query($filter$options);
$cursor $manager->executeQuery('db.collection'$query);

foreach (
$cursor as $document) {
    
var_dump($document);
}

?>

If the query fails to complete after one second of execution time on the server, a MongoDB\Driver\Exception\ExecutionTimeoutException will be thrown.
