MongoGridFSFile::getResource — Returns a resource that can be used to read the stored file
This method returns a stream resource that can be used with all file functions in PHP. The contents of the file are pulled out of MongoDB on the fly, so that the whole file does not have to be loaded into memory first.
At most two GridFSFile chunks will be loaded in memory.

This function is not implemented yet, as I get the following error every time I try to use this function:
PHP Fatal error: Call to undefined method MongoGridFSFile::getResource()
I understand it says ((o version information available, might only be in SVN) at the top, but just giving people a heads up.
