Example #1 MongoDB\Driver\Cursor::getId() example
<?php
$manager = new MongoDB \ Driver \ Manager ( "mongodb://localhost:27017" );
$query = new MongoDB \ Driver \ Query ([], [ 'batchSize' => 2 ]);
$bulk = new MongoDB \ Driver \ BulkWrite ;
$bulk -> insert ([ 'x' => 1 ]);
$bulk -> insert ([ 'x' => 2 ]);
$bulk -> insert ([ 'x' => 3 ]);
$manager -> executeBulkWrite ( 'db.collection' , $bulk );
$cursor = $manager -> executeQuery ( 'db.collection' , $query );
var_dump ( $cursor -> getId ());
?>
以上例程的输出类似于:
object(MongoDB\Driver\CursorId)#5 (1) { ["id"]=> int(94810124093) }
