Stores a file in the database

public MongoGridFS::put ( string $filename [, array $metadata = array() [, array $options = array() ]] ) : mixed

Note:
MongoGridFS::put() is an alias of MongoGridFS::storeFile().

filename: Name of the file to store.
metadata: Other metadata fields to include in the file document.

Note:
These fields may also overwrite those that would be created automatically by the driver, as described in the MongoDB core documentation for the » files collection. Some practical use cases for this behavior would be to specify a custom chunkSize or _id for the file.
options: An array of options for the insert operations executed against the chunks and files collections. See MongoCollection::insert() for documentation on these these options.

Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the metadata parameter.

Throws MongoGridFSException if there is an error reading filename or inserting into the chunks or files collections.
