The MongoCollection class
(PECL mongo >=0.9.0)
Introduction
Represents a MongoDB collection.
Collection names can use any character in the ASCII set. Some valid collection names are "", "...", "my collection", and "*&#@".
User-defined collection names cannot contain the $ symbol. There are certain system collections which use a $ in their names (e.g., local.oplog.$main), but it is a reserved character. If you attempt to create and use a collection with a $ in the name, MongoDB will assert.
