Hi all,

I read online about a way to "force" a file download dialog box using the Content-Disposition header combined with fpassthru() in PHP, like so:

(query string is to be specified as a filename - without path - to a file in the current working directory)

$filename = getenv('QUERY_STRING');
$stuff = preg_split( "/\./", $filename );
$ext  = array_pop( $stuff );
$mime = array(
    "html" => "text/html",
    "htm"  => "text/html",
    "txt"  => "text/html",
    "rtf"  => "application/rtf",
    "doc"  => "application/msword",
    "zip"  => "application/zip",
);
header( 'Content-Type: ' . $mime[ strtolower( $ext ) ] );
header( "Content-Disposition: attachment;filename=$filename" );
$h = fopen( $filename, 'r' );
fpassthru( $h );
fclose( $h );
exit();

It works fine, but for some reason whenever it passes a text file (.txt), all the newlines are removed after downloading it. doc/html/htm/zip files download flawlessly.

Anyone offer some insight into this, particularly how to transfer txt files properly?

Thanks in advance

Because you have:
"txt" => "text/html"
which should be:
"txt" => "text/plain"
