$namespace, MongoDB\Driver\Query $query, array $options = array()): MongoDB\Driver\Cursor
Selects a server according to the "readPreference" option
and executes the query on that server. By default, the read preference from
the MongoDB Connection
URI will be used.

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.
