How to create GridFS collection?

I have read a number of documents till now on MongoDB and am interested in creating a GridFS collection to store files. I already have created the PHP script which can deal with files stored in MySQL (blob datatype) and it is working. However I now need to work with GridFS. PHP Driver documents confused me.

NOTE: The point that confuses me is - they do not tell how to create the 'chunks' collection. There are no guidelines. If it is so then how can I expect the driver to be able to read the files from the 'files' collection automatically?

Can someone point me to a page where it has been explained how to create one? Or may be help me understand the 'expectations' of language drivers for GridFS collection(s?).

Regards Vaibhav

Looking through the PHP documentation I found the following manual on how to store data in a GridFS Collection: PHP GridFS Manual. I don't have any specific knowledge from PHP but in Java I do the following:

GridFS gridFS = new GridFS(<DB_NAME>, <GRID_FS_COLLECTION>);
GridFSInputFile inputFile = gridFS.createFile(<BINARY_DATA>);
inputFile.put("documentName", "nameOfTheFile");
inputFile.put("extension", "txt");
inputFile.save();

Looking at the PHP Manual it would be something similar to this in PHP:

<?php
   $grid = $db->getGridFS();
   $grid->storeBytes($bytes, array("documentName" => "nameOfTheFile", "extension" => "txt"));
?>

The examples in the manual also show a way to store a file directly without getting a string of bytes first.
