File Streaming Problem

[XiaoRulez]

Heres what i got:

session_start();
function send_file($path, $name) {
   ini_set("max_execution_time", "".(60*60*24)); // 24 hours
   header('Content-Description: File Transfer');
   header('Content-Type: application/octet-stream');
   header('Content-Length: '.filesize($path));
   header('Content-Disposition: attachment; filename="'.$name.'"');
   header("Pragma: no-cache");
   header("Expires: 0");

   $fp = fopen($path, 'rb');
   while(!feof($fp)) {
      if(connection_aborted()) die();
      echo fread($fp, 1024);
      flush();
   }
   fclose($fp);
}
if (@$_SESSION['fid'] == base64_encode(session_id()))
   send_file(base64_decode($_SESSION['file']),base64_decode($_SESSION['fname']));

 

Now, heres my problem;

Everything works fine exept rar files, i tryed: rar, zip, txt, asm

a 302 byte rar file only sends 287 bytes :S i checked the filelength, which was 302 in the header.

 

maybe something in in the rar's end of file?

oh, and 1 more funny thing, if i remove the content-length header, it works. but i need it...

 

output for

die('Content-Length: '.filesize($path));

was Content-Length: 302

 

Apache 1.3.X, PHP 5.1

okok, i got news... lol, it works under FlashGet (a download manager), but not firefox or ie or even opera 8...

in IE it displays as 287 bytes after download, but in opera, it displays as the correct 302b, however, only 302 is downloaded...

 

:S i really need this done, i'm expecting this script to go live in a week or 2 Y_Y

try adding

header("Content-Transfer-Encoding: binary");

[XiaoRulez]

:S nope, "header("Content-Transfer-Encoding: binary");" dosn't fix it.

 

it always has problems at the last % or so... wither the files are large or small... maybe the connection is cut just before it finish's...

 

need my phpinfo for a better idea?

[MadTechie]

try

 

change

   $fp = fopen($path, 'rb');
   while(!feof($fp)) {
      if(connection_aborted()) die();
      echo fread($fp, 1024);
      flush();
   }
   fclose($fp);

to

readfile($path);

 

when the file downloads.. open it in wordpad and check the top to see if theirs any php output (ie errors)

[XiaoRulez]

:S i don't want to use readfile, because as some of the files are WAY over 100mb, i really don't wanna blow my memory by loading 100 megs into it with readfile :S

[XiaoRulez]

i did this:

$s=fread($fp, $block_size);
echo(''.strlen($s));

302...lol

but when i have

echo($s);

only echos 287 characters...

 

maybe archives have special characters :S, cos it works with practically every other file type... damages rar, zip, even uha :S couldn't try ace... can't afford it

 

rmvb's, and avi's seem perfect.

 

i was also wondering if there was a way for the script to load like a buffer? cos it's just sending the whole file as fast as it can (ie. HDD goes crazy for about a few seconds, then stops...lol)

[MadTechie]

with zip files i had a ton of problems, (i created the zip on the fly)

 

i used this and it works perfectly

 

<?php
$archiveName = "whatever.zip";
if(ini_get('zlib.output_compression')) {
	ini_set('zlib.output_compression', 'Off');

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/zip");
header("Content-Disposition: attachment; filename=".basename($archiveName).";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($archiveName));
readfile("$archiveName");
exit;
?>

 

as for readfile vs fread i have had less problems with readfile (try decreaseing the block size on fread, see how that affects it)

[XiaoRulez]

well, for the time being, I'm taking out the content length, it seems to fix it up a bit. what would happen if i set the content just a kb over the actual? will people die?
