Описание
public resource MongoGridFSFile::getResource

This method returns a stream resource that can be used with all file functions in PHP that deal with reading files. 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.
