Changelog
Version | Description |
---|---|

Examples
Example #1 MongoCursor::info() example
<?php$m = new MongoClient();$cursor = $m->test->foo->find(array("x" => 4), array("y" => 0));echo "Before iteration started:\n";var_dump($cursor->info());echo "\nAfter iteration started:\n";$cursor->rewind();var_dump($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" }
