ID: 46171 Updated by: [EMAIL PROTECTED] Reported By: Keisial at gmail dot com Status: Open Bug Type: Streams related Operating System: * PHP Version: 5.3CVS-2008-09-25 (snap) New Comment:
The problem is that the stream is partially closed (resource deleted) when filter() is called with $closing==true. That is, $this->stream is not a valid resource at this point. You may want to fflush() the stream before closing, and not use ->stream when closing. Don't know if it's a bug or documentation problem (actually, not making the stream resource available during fclose() is not that bad).
