If you want to force download large files, you will not fall into memory_limit with this script :
if (!is_file($file)) { die("<b>404 File not found!</b>"); }
$len = filesize($file);
$filename = basename($file);
$file_extension = strtolower(substr(strrchr($filename,"."),1));
header('Content-type: application/force-download');
header('Pragma: public');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Disposition: attachment; filename="' . $filename .
'"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: '.$len);
header('Location: '.$file);
$chunksize = 1*(1024*1024); // how many bytes per chunk
$buffer = '';
$handle = fopen($file, 'rb');
if ($handle === false) {
die("Handle not received");
}
while (!feof($handle)) {
$buffer = fread($handle, $chunksize);
echo $buffer;
flush();
}
exit;
