In order to get all the documents in the collection, we will use
<span class="function"><a href="mongocollection.find.html" class="function">MongoCollection::find()</a></span>. The find() method returns a
<a href="class.mongocursor.html" class="classname">MongoCursor</a> object which allows us to iterate over the
set of documents that matched our query. So to query all of the documents and
print them out:

and that should print all 101 documents in the collection.
<em>$id</em> is the <em>_id</em> field of a document
