The following piece of code handles detection of mime type, file size and existence of the file for you. I always use this piece for buffering files into browser of my users.
if (file_exists($fileLocation)) {
header('Content-Description: File Transfer');
header('Content-Type: ' .mime_content_type($fileLocation));
header('Content-Disposition: attachment; filename="'.basename($fileLocation).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($fileLocation));
readfile($fileLocation);
exit;
}
All you have to do is to change the variable of $filelocation with your own variable which contains the full address of your local file.
Hope it helps some of you out there.
