forgot to mention, they can't right click to save as because if you
notice from my code i am pushing the file to them... without an actual

The Content-disposition header is a made-up bull-crap thing that came
about with html enhanced (cough, cough) email.
If you want *EVERY* browser to download something, forget this header and
use:
header(Content-type: application/octet-stream);
The Content-disposition will, on *SOME* browsers, on *SOME* OSes appear to
be useful for getting the filename in the dialog prompt for Save As...
to be the filename you want.
Unfortunately, it does *NOT* work universally.
If you want a UNIVERSAL solution, make the URL look like it's a static
URL and have the filename you want to be used appear at the end of the
URL.
Converting dynamic to static-looking URLs is covered in many places.
Google for PHP $_SERVER PATHINFO
Under no circumstances should you be using headers like audio/mpeg if
you want me to download it -- I guarantee my browser will open that up in
an MP3 player. Many other users will also have been led through the
process to make that happen.
But if the browser doesn't download application/octet-stream it's a very
very very broken browser.

if i don't use Content-disposition IE downloads the file as unknown
(mp3, exe, or otherwise) with no extension and the names the file you
are downloading becomes the name of the script that was called. lol?

So here's what you do. Go ahead and RENAME your PHP script to next_hit_song.mp3 Then use .htaccess to tell Apache that it's *REALLY* a PHP script even though it ends in .mp3 Files next_hit_song.mp3 application/x-httpd-php /Files That is what I mean by making the URL look static IE is so [bleeping] stupid about URLs and content-type and rich media, that you simply cannot give it any room for a mistake. Consider the MP3s and m3u s on the pages here: http://uncommonground.com/ http://uncommonground.com/artist_profile/Ellen+Rosner Every one of the MP3/m3u files you can find there is really a PHP script. They just happen to end in .mp3 and .m3u so IE can't [bleep] up. The dynamic MP3 downloads (and streams) have the MP3 ID3 tags inserted at download time, so the artists can correct typos or give me info like song title and whatnot lonnng after the actual mp3 is created, identified, and cataloged. The m3u playlists are coming out the database from queries with all kinds of interesting properties. New playlist every day on the homepage. Different playlist every download on the calendar pages: http://uncommonground.com/events.htm While you are there, check out that PDF. Yup. That ain't really a PDF, it's a PHP script. But even IE can't manage to screw up when the URL is http://uncommonground.com/events.pdf I do need to fix the ones where the date (past/future months) is passed as a GET argument. Some versions of IE on the Mac mess that up. Sigh.

Re: [PHP] force download with header()
Are you using Internet Explorer? Then it's a feature of IE--it ignores
the disposition headers sent by your server because its registry tells
it that PDF files must be viewed inline. There's a way around it,
although it's a bit kludgy--I wrote a small article about it that you
can find here (it's in PDF format, as well):
http://www.phparch.com/issuedata/2002/december/sample.php
Essentially, you're telling IE to download a file with the extension
.pdf (not the space) so that it can't match the MIME type anymore and
will follow your suggestion of downloading the file instead of
displaying it inline.
Hope this helps!
Cheers,
Marco

i was reading about php.net looking for a way to force a download of a txt file,
rather than the browser displaying the file.
i ran into header() that seems to be able to accomplish it... but seeing as i'm very
much a newbie at php, i can't seem to make this work
if the file i want to download is
nfo/60/ind.txt
how would i impliment this:
?php
// We'll be outputting a PDF
header(Content-type: application/pdf);
// It will be called downloaded.pdf
header(Content-Disposition: attachment; filename=downloaded.pdf);
// The PDF source is in original.pdf
readfile('original.pdf');
?

Re: [PHP] force download and file size issue
readfile() reads 8k blocks at a time and dumps them out. It does not read the entire thing into ram, so that wouldn't be what was causing you to hit a memory limit.
