having a problem with large downloads from a htaccess protected directory. Currently I'm using this:
version 1:
set_time_limit(0);
$item=$chkrow->files;
//force download - should bring up save box, but it doesn't!
$dload=$dir_upload.$item;
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/force-download");
// it even allows spaces in filenames
header('Content-Disposition: attachment; filename="'.$item.'"');
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($dload));
readfile("$dload");
exit();But it fails for large downloads, so I have tried replacing readfile with: eshop_readfile($dload);
Which leads to:
if (!function_exists('eshop_readfile')){
// Read a file and display its content chunk by chunk
function eshop_readfile($filename, $retbytes = TRUE) {
$buffer = '';
$cnt =0;
$chunksize=1024*1024;// Size (in bytes) of tiles chunk
$handle = fopen($filename, 'rb');
if ($handle === false) {
return false;
}
while (!feof($handle)) {
$buffer = fread($handle, $chunksize);
echo $buffer;
ob_flush();
flush();
if ($retbytes) {
$cnt += strlen($buffer);
}
}
$status = fclose($handle);
if ($retbytes && $status) {
return $cnt; // return num. bytes delivered like readfile() does.
}
return $status;
}
}But apparently that doesn't work either.
So I'll assume I'm doing something wrong, and ask for help!
Remember: download directory is htaccess protected.
