添加标题不会使文件下载

It's pretty well documented that adding a header is the way to make a link downloadable, but I must be doing something wrong. I write the file, and then produce some HTML linking to it, but the file will not download, only appear in the browser.

<?

   //unique id
   $unique = time();

   $test_name = "HTML_for_test_" . $unique . ".txt";

   //I should put the file name I want the header attached to here (?)
   header("Content-disposition: attachment;filename=$test_name");

   $test_handler = fopen($test_name, 'w') or die("no");

   fwrite($test_handler, $test);
   fclose($test_handler);

?>

<a href="<?=$test_name">Download File</a>

    Well you are just echoing an HTML tag - you should read the file content instead, like proposed on PHP Doc:

    <?php
    $file = 'monkey.gif';
    
    if (file_exists($file)) {
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename='.basename($file));
        header('Content-Transfer-Encoding: binary');
        header('Expires: 0');
        header('Cache-Control: must-revalidate');
        header('Pragma: public');
        header('Content-Length: ' . filesize($file));
        ob_clean();
        flush();
        readfile($file);
        exit;
    }
    ?>
