note 16127 added to function.header

I have a design using php/mysql. In mysql database i stored multimedia files such as avi, mp3, as blob types. How can I stream such files using headers maybe, through an internet browser. I have available the binarydata, filename, filesize and filetype. Till now with: header("Content-type: $filetype"); the appropriate program is being lauched in the internet brower (IE) without playing anything as the php file is being inserted in the appropriate program. What should I do? -- http://www.php.net/manual/en/function.header.php http://master.php.net/manage/user-notes.php?action=edit+16127 http://master.php.net/manage/user-notes.php?action=delete+16127 http://master.php.net/manage/user-notes.php?action=reject+16127
