MongoCollection::__get — Gets a collection
A concise syntax for getting a collection with a dot-separated name. If a collection name contains strange characters, you may have to use MongoDB::selectCollection() instead.
$mongo = new Mongo();
// the following two lines are equivalent
$collection = $mongo->selectDB("foo")->selectCollection("bar.baz");
$collection = $mongo->foo->bar->baz;
The next string in the collection name.
Returns the collection.
