EXAMPLES

       Example #1

	      MongoCursor.info(3) example

	      <?php
	      $m = new MongoClient();

	      $cursor = $m->test->foo->find(array("x" => 4), array("y" => 0));

	      echo "Before iteration started:
";
	      var_dump($cursor->info());

	      echo "
After iteration started:
";
	      $cursor->rewind();
	      var_dump($cursor->info());

	      ?>

	      The above example will output something similar to:

	      Before iteration started:
	      array(8) {
		["ns"]=>
		string(8) "test.foo"
		["limit"]=>
		int(0)
		["batchSize"]=>
		int(0)
		["skip"]=>
		int(0)
		["flags"]=>
		int(0)
		["query"]=>
		array(1) {
		  ["x"]=>
		  int(4)
		}
		["fields"]=>
		array(1) {
		  ["y"]=>
		  int(0)
		}
		["started_iterating"]=>
		bool(false)
	      }

	      After iteration started:
	      array(15) {
		["ns"]=>
		string(8) "test.foo"
		["limit"]=>
		int(0)
		["batchSize"]=>
		int(0)
		["skip"]=>
		int(0)
		["flags"]=>
		int(0)
		["query"]=>
		array(1) {
		  ["x"]=>
		  int(4)
		}
		["fields"]=>
		array(1) {
		  ["y"]=>
		  int(0)
		}
		["started_iterating"]=>
		bool(true)
		["id"]=>
		int(0)
		["at"]=>
		int(0)
		["numReturned"]=>
		int(1)
		["server"]=>
		string(25) "localhost:27017;-;.;26450"
		["host"]=>
		string(9) "localhost"
		["port"]=>
		int(27017)
		["connection_type_desc"]=>
		string(10) "STANDALONE"
	      }
