The MongoGridFS class

Introducere

Utilities for storing and retrieving files from the database.

MongoGridFS extends MongoCollection, so any of the methods in MongoCollection can be used to manipulate metadata. For example:


<?php

// save a file
$id = $grid->storeFile("game.tgz");
$game = $grid->findOne();

// add a downloads counter
$game->file['downloads'] = 0;
$grid->save($game->file);

// increment the counter
$grid->update(array("_id" => $id), array('$inc' => array("downloads" => 1)));

?>
