For the following code, can I get an opinion on what exactly the browser
will "do" or "receive" when the function returns false?
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/octet-stream");
header("Content-Length: " . filesize($val));
$filename = explode("/",$val);
$parts = count($filename);
header("Content-Disposition: attachment; filename=".$filename[$parts-1]);
function readfile_chunked($filename) {
$chunksize = 1*(1024*1024); // how many bytes per chunk
$buffer = '';
$handle = fopen($filename, 'rb');
if($handle === false) { return false; }
while (!feof($handle)) {
$buffer = fread($handle, $chunksize);
print $buffer;
}
return fclose($handle);
}
readfile_chunked($val);
exit;

Exactly what you sent - the headers and nothing else.
