Counting Documents in A Collection

Now that we've inserted 101 documents (the 100 we did in the loop, plus the first one), we can check to see if we have them all using the MongoCollection::count method.


<?php
$connection = new MongoClient();
$collection = $connection->database->collectionName;

echo $collection->count();
?>

and it should print 101.
