例

例1 MongoCommandCursor::info() example


<?php
$m = new MongoClient();
$c = $m->test->test;
$cursor = $c->commandCursor( [
    'aggregate' => 'test', 
    'pipeline' => [ 
        [ '$match' => [ '_id' => [ '$exists' => true ] ] ],
    ]
] );

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

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

?>

上の例の出力は、たとえば以下のようになります。

Before iteration started:
array(8) {
  'ns' =>
  string(9) "test.test"
  'limit' =>
  int(0)
  'batchSize' =>
  int(0)
  'skip' =>
  int(0)
  'flags' =>
  int(0)
  'query' =>
  array(2) {
    'aggregate' =>
    string(4) "test"
    'pipeline' =>
    array(1) {
      [0] =>
      array(1) {
        '$match' =>
        array(1) {
          '_id' =>
          array(1) {
            '$exists' =>
            bool(true)
          }
        }
      }
    }
  }
  'fields' =>
  NULL
  'started_iterating' =>
  bool(false)
}
Aftere iteration started:

  int(101)

          }
        }
      }
    }
