PHP problem when dowloading to browser using headers

I'm creating zip files to update through recovery of custom roms.

My web app creates a zip, if I use it (copying from www/webapp to phone) it's all ok. But when I download it through browser, that I do using: ($zipfile is "something.zip")

MIDL

// Send file headers
    header("Content-type: application/zip");
    header("Content-Disposition: attachment;filename=$zipfile");
    readfile($zipfile);

I can see and open it in my PC (it looks perfectly ok) but in my phone I get "can't open something.zip - (bad).

I already tried a lot of combinations of headers parameteres but no sucess. The file is also a couple KB larger than the original one (the one it works, at webapp directory) - i dont know if it's suppose, but it's something different.

Can you help me please?

That would be the solution

C#

if (file_exists($zipfile)) {
        header('Content-Description: File Transfer');
        header('Content-Type: application/zip');
        header('Content-Disposition: attachment; filename='.basename($zipfile));
        header('Content-Transfer-Encoding: binary');
        header('Expires: 0');
        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
        header('Pragma: public');
        header('Content-Length: ' . filesize($zipfile));
        ob_clean();
        flush();
        readfile($zipfile);
        exit;
    }
