Question

I want to encode binary file into base64 and put it into php page (inline with the code), And when request that page it streams the file to the browser,popup a download dialog.

Any ideas

Answer 1

Seems pretty straightforward. As with readfile, use http headers to force download, and then echo the encoded string.

$decoded_data = base64_decode($encoded_data);

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . strlen($decoded_data);
ob_clean();
flush();
echo $decoded_data;
exit;
