MongoCommandCursor::info — Gets information about the cursor's creation and iteration
This can be called before or after the cursor has started iterating.
この関数にはパラメータはありません。
Returns the namespace, batch size, limit, skip, flags, query, and projected fields for this cursor. If the cursor has started iterating, additional information about iteration and the connection will be included.
例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());
?>
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(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) }
