MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$Bool = $MadelineProto->upload->saveFilePart(['file_id' => long, 'file_part' => int, 'bytes' => 'bytes', ]);

Or, if you're into Lua:

Bool = upload.saveFilePart({file_id=long, file_part=int, bytes='bytes', })
