Uploading/retrieving binary files into Oracle??

Can anyone point me to some sample code for uploading and later retrieving PDFs or other binary files into an Oracle BLOB field? I've been searching for some time and haven't been able to come up with anything. It looks like there's new LOB functions for OCI but they aren't documented at all on the PHP site. Does anyone have a good tutorial or sample code on doing something like this. Thanks in advance for any assistance.
