<?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());
?>
Yukarıdaki örnek şuna benzer bir çıktı üretir:
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) {

}
}
["cursor"]=>
array(1) {
["batchSize"]=>
int(1)
}
}
["fields"]=>
NULL
["started_iterating"]=>
bool(false)
}
After iteration started:
