PHP File Downloads all stop exactly at 1GB

Question

I have a script setup so users can download files via a php script (one time use link) however when the file size reaches 1GB it fails to download any further.

It stops exactly at 1GB

Is there some setting in php.ini that would allow me to adjust it to go beyound 1GB? I have tried changing most of the settings below but i dont see anything that would relate to a 1GB file size ...

Example: www.url.com/file.php?download=filename.zip (uses the below php code)

<?php
 $DownloadableFilesDirectory = "/dl/secret";
 $FileRenamePrependCharacters = "odroid_";

 if( ! empty($FileRenamePrependCharacters) ) { $FileRenamePrependCharacters = 
 ltrim($FileRenamePrependCharacters); }
 $DownloadableFilesDirectory = 
 preg_replace('/^\/*/','/',$DownloadableFilesDirectory);
 $DownloadableFilesDirectory = 
 preg_replace('/\/*$/','',$DownloadableFilesDirectory);
 $Directory = $_SERVER['DOCUMENT_ROOT'].$DownloadableFilesDirectory;
 if( empty($_GET['download']) ) { exit; }
 if( empty($_GET['savefile']) ) { $_GET['savefile'] = $_GET['download']; }
 $Dfile = $Directory.'/'.$_GET['download'];
 $size = filesize($Dfile);
 if( ! $size )
{
    echo '<p><b>The download file is empty or was not located.</b></p>';
    exit;
 }
 $ctype = 'application/octet-stream';
 header('Cache-control: private');
 header("Content-Type: $ctype");
 header('Content-Disposition: attachment; filename="'.$_GET['savefile'].'"');
 header('Content-Transfer-Encoding: binary');
 header("Content-Length: $size");
 @readfile($Dfile);
 if( empty($FileRenamePrependCharacters) ) { unlink($Dfile); }
 else
 {
    $pieces = explode('/',$Dfile);
    $pieces[count($pieces)-1] = $FileRenamePrependCharacters . 
 $pieces[count($pieces)-1];
    rename($Dfile,implode('/',$pieces));
  }
 exit;
 ?>

what is your server? Apache or nginx? There are settings to limit download in Apache. — jagad89, Aug 02 '18 at 13:06

Maybe you reaches the max_execution_time limit, it depends on the way you send the file. — Jordan Breton, Aug 02 '18 at 13:08
Let me rephrase: what is the PHP code you use to enable that download? — deceze, Aug 02 '18 at 13:08
Hopefully you're streaming the file and aren't loading the file entirely in memory. — Daan, Aug 02 '18 at 13:10
@deceze it might help to never use `@` at all, in my opinion, even for experienced devs. Have you tried to expand the max_execution_time to see if it send more than 1GB ? — Jordan Breton, Aug 02 '18 at 13:16
Yes i have, i set the max_execution_time to 500000000000000000 no change — Douglas Littlefield, Aug 02 '18 at 13:20
maybe you should try the `set_time_limit(0)` directive in the begenning of your file. I'm not sure a large number like the one you set can be handled correctly accordingly to the architecture of your server... — Jordan Breton, Aug 02 '18 at 13:21

unless you're getting errors like PHP Fatal error: Maximum execution time of ??? seconds exceeded in foo.php on line ? in the error log, or being stupid and saving all the downloaded contents in ram and get errors like PHP Fatal error: Allowed memory size of ??? bytes exhausted (tried to allocate ??? bytes) in foo.php on line ? in the error log (and you're not doing that, going by the code you posted), this is not a PHP problem, it's a problem with the web server you're using. (nginx? apache? lighthttpd? microsoft's IIS? some proxy? some load balancer ala Cloudflare?), start your investigation there.

the readfile() function doesn't load the entire file in memory. And a lack of experience or knowledge is not a proof of stupidity :/ – Jordan Breton Aug 02 '18 at 13:25
I just looked at php.ini settings it says Server API LiteSpeed V7.1 PHP Version 7.0.3 – Douglas Littlefield Aug 02 '18 at 13:30

@DouglasLittlefield then check the LiteSpeed configuration / error logs, the problem is almost certainly with LiteSpeed – hanshenrik Aug 02 '18 at 13:36
@DouglasLittlefield and what configuration is it using? – hanshenrik Aug 02 '18 at 13:55
would it do any harm if i post the link to view the php.ini settings? – Douglas Littlefield Aug 02 '18 at 13:58
@DouglasLittlefield in the vast majority of cases, no. for example, here is 1 of my servers: http://ratma.net/phpinfo.php - however, if you use the `mysql.default_user` / `mysql.default_password` / `mysqli.default_pw` php.ini configuration options, then it's a problem. check for these options before publishing the ini. (but actually using those settings is a terrible design choice anyway..) – hanshenrik Aug 02 '18 at 15:46
