Large File download issue

[PHP Programming]

Hello,

 

I am working on a project that downloads large zip files from server, for small files the script works well and downlaod files successfully, but for larger files like currently we are trying to download a 922MB file it gives us this message (in firefox) and doesn't download any thing.

 

"

File not found

 

Firefox can't find the file at http://www.domainname.com/abc.zip

 

"

Script to download the file is as below:

 

"

$filename = "xyz.mp3;

 

header("Pragma: public");

header("Expires: 0");

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

 

header("Content-Type: application/force-download");

header("Content-Type: application/octet-stream");

header("Content-Type: application/download");

 

header("Content-Disposition: attachment; filename=".basename($filename).";");

 

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

header("Content-Length: ".filesize($filename));

 

if( !ini_get('safe_mode') )

set_time_limit(360000000);

 

readfile("$filename");

"

 

Please advise what can be issue, if its file size issue then how and where can we increase the limit to solve this issue.

 

pre-thanks,

For large files use the function passthru()

 

<?php
$path = '/full/path/to/file/';
$filename = 'xyz.mp3';

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=".$filename.";");				
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($path.$filename));
passthru("cat \"$path.$filename\"");
exit();
?>
