Please, help!

What exactly are you trying to do? From the top section it seems like you're trying to output back via the standard output channel, meaning as the body of a response. This assumes you're working in a client/server relationship, where PHP is invoked server-side as a script, and its response is being sent back to the client (browser). But then all of a sudden, you start opening php://output which is an output stream which exists solely in the cli-mode! So, your answer is simply: 1. in the case of a browser/server type of relation: <?php header("Content-Description: File Transfer"); header("Content-Disposition: attachment; filename=f.txt.bz2"); header("Content-Type: application/x-bzip2"); header("Content-Transfer-Encoding: binary"); $compressed_string = bzcompress("hi"); echo $compressed_string; 2. In the case that you're using php-cli, get rid of all the header stuff. It's useless here. - Tul
