Header download without echoing.

[newbtophp]

Hmm i have a problem, im encoding a string and writing it to a file, and then downloading it using header() however i want the downloaded file to contain the decoded string (base64_decode), but i need to do this without echoing/printing the decoded output or writing the decoded output anywhere? (like readfile),

 

my code:

 

<?php

$file = 'file.txt';

$handle = fopen($file, "w");
fwrite($handle, base64_encode($string));
fclose($handle);

    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
//decode it in memory without echoing or writing it anywhere...
    readfile(base64_decode($file));
    exit;

?>

 

PS: Cant really explain why i specifically need it to be decoded in memory (so its not echo'd or written anywhere). - as it would be tough to explain.

Anyone? 

 

Perhaps changing:

 

header('Content-Transfer-Encoding: binary');

 

too:

 

header('Content-Transfer-Encoding: base64'); ?
