Example #1 MongoCommandCursor::info() example


<?php
$m = new MongoClient();

$cursor = new MongoCommandCursor(
    $m, // MongoClient object
    'demo.cities', // namespace
    [
        'aggregate' => 'cities',
        'pipeline' => [ [ '$match' => [ '_id' => [ '$exists' => true ] ] ] ],
        'cursor' => [ 'batchSize' => 1 ],
    ]
);

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

echo "\nAfter iteration started:\n";
$cursor->rewind();
var_dump($cursor->info());

?>

Il precedente esempio visualizzerà qualcosa simile a:

Before iteration started:
array(8) {
  ["ns"]=>
  string(11) "demo.cities"
  ["limit"]=>
  int(0)
  ["batchSize"]=>
  int(0)
  ["skip"]=>
  int(0)
  ["flags"]=>
  int(0)
  ["query"]=>
  array(3) {
    ["aggregate"]=>
    string(6) "cities"
    ["pipeline"]=>
    array(1) {
      [0]=>
      array(1) {
        ["$match"]=>
        array(1) {
          ["_id"]=>
          array(1) {
            ["$exists"]=>
            bool(true)
          }
        }
      }
    }
    ["cursor"]=>
    array(1) {
      ["batchSize"]=>
      int(1)
    }
  }
  ["fields"]=>
  NULL
  ["started_iterating"]=>
  bool(false)
}

After iteration started:
array(17) {
  ["ns"]=>
  string(11) "demo.cities"
  ["limit"]=>
  int(0)
  ["batchSize"]=>
  int(0)
  ["skip"]=>
  int(0)
  ["flags"]=>
  int(0)
  ["query"]=>
  array(3) {
    ["aggregate"]=>
    string(6) "cities"
    ["pipeline"]=>
    array(1) {
      [0]=>
      array(1) {
        ["$match"]=>
        array(1) {
          ["_id"]=>
          array(1) {
            ["$exists"]=>
            bool(true)
          }
        }
      }
    }
    ["cursor"]=>
    array(1) {
      ["batchSize"]=>
      int(1)
    }
  }
  ["fields"]=>
  NULL
  ["started_iterating"]=>
  bool(true)
  ["id"]=>
  int(185840310129)
  ["at"]=>
  int(0)
  ["numReturned"]=>
  int(0)
  ["server"]=>
  string(25) "localhost:27017;-;.;23991"
  ["host"]=>
  string(9) "localhost"
  ["port"]=>
  int(27017)
  ["connection_type_desc"]=>
  string(10) "STANDALONE"
  ["firstBatchAt"]=>
  int(0)
  ["firstBatchNumReturned"]=>
  int(1)
