In the earlier example, we used the getBytes() method of the MongoGridFSFile class to read the contents of a file. We learned that there is a potential problem with this approach, getBytes() attempts to load the entire content of the file into memory. Reading large files in this way may affect performance negatively. But there is a way to get around this problem. As we know that in GridFS a file's contents are split into chunks, we could use the PHP driver to read and output the data of each chunk individually, thus avoiding dumping the entire content into memory. In the next example we are going to see how we can do that.
