Download file

[Anon]

Hello !

I have a binary-file on my server, which is 17236097 bytes long. You can
download this file with the following script:

    Header( "Content-type: $this->mime");
    Header( "Content-Disposition: attachment; filename=$filename" ); 
    Header( "Content-Description: My Generated Data" );
    $fp = fopen($filename, "r");
    while (!feof ($fp))
    {       $buffer = fgetc($fp);
            print $buffer;
    }
    fclose($fp);

The downloaded file then on my harddisc is 16723744 bytes long. I tried it also with fgets, fread and set_magic_quotes_runtime(false); - no effect.

Any ideas why some bytes are missing ?

What OS are the server and client running on?
You can and will (must!) get a different length
on text files between DOSWin and Unix.

The server is indeed unix and the client is windows. But:

1.) It's a binary file, so how can I tell php to copy the file 1:1 ?

2.) When using ftp to copy the file from server to client, it length is:
- 17236097 (the original size) when using binary mode
- 17481992 (larger then original size) when using ascii mode
But with PHP, it's smaller.

BTW: The mime-type is: "application/x-gzip", so no Ascii-conversion should be done by the browser.

1.) It's a binary file, so how can I tell php to copy the file 1:1 ?

Perhaps using the php function copy()? But again, unless it's
cross-volume, rename() or link() will be much better because
they doesn't have to move any data, they just creates a new
directory entry. And if it is cross-volume, and your site gets
lots of this kind of activity, it's worth symlinking the upload
directory so it is on the same volume as the ultimate destination.

2.) When using ftp to copy the file from server to client, it length is:
- 17236097 (the original size) when using binary mode
- 17481992 (larger then original size) when using ascii mode

That's normal and to be expected.

But with PHP, it's smaller.

Something is definitly broken, but before you panic() try copy()
or link() first.

Hi,

Funny enough, I answerd a similar question earlier today about downloading PDF-files. See http://www.phpbuilder.com/forum/read.php3?num=2&id=111410&thread=111404

Hiya
I am using just one line
readfile($file);
and it seems working fine
