MONGOCOMMANDCURSOR.__CONSTRUCT(3) 1 MONGOCOMMANDCURSOR.__CONSTRUCT(3) MongoCommandCursor::__construct - Create a new command cursor SYNOPSIS
public MongoCommandCursor::__construct (MongoClient $connection, string $ns, array $command = array()) DESCRIPTION
Generally, you should not have to construct a MongoCommandCursor manually, as there are helper functions such as MongoCollection::aggre- gateCursor and MongoCollection::parallelCollectionScan; however, if the server introduces new commands that can return cursors, this con- structor will be useful in the absence of specific helper methods. You may also consider using MongoCommandCursor::createFromDocument. PARAMETERS
o $connection - Database connection. o $ns - Full name of the database and collection (e.g. "test.foo") o $command - Database command. RETURN VALUES
Returns the new cursor. EXAMPLES
Example #1 MongoCommandCursor example <?php $m = new MongoClient; // Define the aggregation pipeline $pipeline = [ [ '$group' => [ '_id' => '$country_code', 'timezones' => [ '$addToSet' => '$timezone' ] ] ], [ '$sort' => [ '_id' => 1 ] ], ]; // Construct a MongoCommandCursor object $cursor = new MongoCommandCursor( $m, // MongoClient object 'demo.cities', // namespace [ 'aggregate' => 'cities', 'pipeline' => $pipeline, 'cursor' => [ 'batchSize' => 0 ], ] ); foreach($cursor as $result) { } ?> SEE ALSO
