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) {

	      }
	      ?>
