Download Stops at 31.2 MB

I got it to work. I adapted the script from another script I found.

Here's what I did:

Just after

Code:

// Browser will try to save file with this filename, regardless original filename.
// You can override it if needed.

if (!isset($_GET['fc']) || empty($_GET['fc'])) {
$asfname = $fname;
}
else {
// remove some bad chars
$asfname = str_replace(array('"',"'",'\\','/'), '', $_GET['fc']);
if ($asfname === '') $asfname = 'NoName';
}

I replaced

Code:

// set headers
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: $mtype");
header("Content-Disposition: attachment; filename=\"$asfname\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . $fsize);

// download
// @readfile($file_path);
$file = @fopen($file_path,"rb");
if ($file) {
while(!feof($file)) {
print(fread($file, 1024*8));
flush();
if (connection_status()!=0) {
@fclose($file);
die();
}
}
@fclose($file);
}

with

Code:

@ob_end_clean(); //turn off output buffering to decrease cpu usage

// required for IE, otherwise Content-Disposition may be ignored
if(ini_get('zlib.output_compression'))
ini_set('zlib.output_compression', 'Off');

// set headers
header("Content-Description: File Transfer");
header("Content-Type: $mtype");
header("Content-Disposition: attachment; filename=\"$asfname\"");
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Pragma: public");
header("Expires: 0");

// multipart-download and download resuming support
if(isset($_SERVER['HTTP_RANGE']))
{
list($a, $range) = explode("=",$_SERVER['HTTP_RANGE'],2);
list($range) = explode(",",$range,2);
list($range, $range_end) = explode("-", $range);
$range=intval($range);
if(!$range_end) {
$range_end=$size-1;
} else {
$range_end=intval($range_end);
}

$new_length = $range_end-$range+1;
header("HTTP/1.1 206 Partial Content");
header("Content-Length: $new_length");
header("Content-Range: bytes $range-$range_end/$size");
} else {
$new_length=$fsize;
header("Content-Length: ".$fsize);
}

/* output the file itself */
$chunksize = 1*(1024*1024); //you may want to change this
$bytes_send = 0;
if ($file = fopen($file_path, 'rb'))
{
if(isset($_SERVER['HTTP_RANGE']))
{ fseek($file, $range); }

while(!feof($file) && (!connection_aborted()) && ($bytes_send<$new_length))
{
$buffer = fread($file, $chunksize);
print($buffer); //echo($buffer); // is also possible
flush();
$bytes_send += strlen($buffer);
}
fclose($file);
}
else { die('Error - cannot open file.'); }

I know that all of those changes probably weren't totally necessary, but it did the trick.
I would love any comments.
I am also extremely interested in another post: Redirect After Download
