Question

I had a code that worked, here:

if (isset($_GET['file']) && isset($_GET['name']))
{
$file = base64_decode($_REQUEST['file']);

$ch = curl_init($file);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);

$data = curl_exec($ch);
curl_close($ch);

if (preg_match('/Content-Length: (\d+)/', $data, $matches)) 
{
    // Contains file size in bytes
    $contentLength = (int)$matches[1];
}

header("Content-type: application/x-file-to-save");
header("Content-Disposition: attachment; filename=".$_REQUEST['name']);
header('Content-Length: ' . $contentLength);
header('Content-Transfer-Encoding: binary');

@readfile($file);

}

And than I changed my server to a differenf host providor, and the code stoped working. When I download from chrome it just keeps loading and loading,
but when I download from a download manager like IDM than it gets the correct name and size, but when I press start it makes an error that says something about not supporting resuming or something…

Again, the code worked when I used a different providor.

Answer 1

It might be errors which are outputted before readfile() use ob_clean();
flush(); to remove any output before readfile
