MongoCursor::info — Gets information about the cursor's creation and iteration
Description

Changelog
Version | Description |
---|---|
1.1.0 | Added a number of other fields, including id (the cursor id), at (the driver's counter of which document is current), numReturned (the number returned by the server in the current batch), and server (which server the query was sent to—useful in conjunction with Read Preferences. |
1.0.10 | Added started_iterating field, a boolean indicating if cursor is pre- or post-query. |
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" }
