PHP mandatory file download

If you need to download a specific file without opening a new window, the following code snippet can help you.

function force_download($file)
{
 $dir = "../log/exports/";
 if ((isset($file))&&(file_exists($dir.$file))) {
 header("Content-type: application/force-download");
 header('Content-Disposition: inline; filename="' . $dir.$file . '"');
 header("Content-Transfer- Encoding: Binary");
 header("Content-length: ".filesize($dir.$file));
 header('Content-Type: application/octet-stream');
 header('Content-Disposition: attachment; filename="' . $file . '"');
 readfile("$dir$file");
 } else {
 echo "No file selected";
 }
}

Usage:

force_download("image.jpg");
?>
