Getting 503 Error on page that loads every other part

[RMorrison]

I've been trying to do this for a while and can't understand why I'm getting a 503 Error. I'm making a download center which counts the downloads of each file, and the only thing I can't get to work is the actual downloading of the file. It took a while for me to realize I was having an issue as my code works perfectly on my home server.

 

Here is my current code:

function download_file_to_user($target_file, $filename) {    global $user;    $mimetype = (strpos(strtolower($user->browser), 'msie') !== false || strpos(strtolower($user->browser), 'opera') !== false) ? 'application/octetstream' : 'application/octet-stream';    $size = @filesize($target_file);    header('Pragma: public');    header("Content-type: $mimetype");    header("Content-Length: $size");    header('Content-Disposition: attachment; ' . header_filename(htmlspecialchars_decode($filename)));    if (empty($user->browser) || (strpos(strtolower($user->browser), 'msie 6.0') !== false))     {           header('expires: -1');    }    else     {        header('X-Download-Options: noopen');    }    @set_time_limit(0);    $fp = @fopen($target_file, 'rb');    if ($fp !== false)    {        while (!feof($fp))        {            echo fread($fp, 8192);        }        fclose($fp);    }    else    {            @readfile($target_file);    }     flush();}

 

$user is a variable storing all the logged in users data. header_filename is another function but it works perfectly.

 

I know at least part of this code is running because I'm getting the following headers:

Cache-Control max-age=0

Connection close

Content-Disposition attachment; filename=Rayths_CMS_Mod_1_3_1.zip

Content-Length 577244

Content-Type application/octet-stream

Date Wed, 19 Nov 2014 18:46:19 GMT

Expires Wed, 19 Nov 2014 18:46:19 GMT

Pragma public

Server nginx

X-Download-Options noopen

X-Powered-By PHP/5.4.35

 

 

What I don't understand is why this is happening. I used multiple guides and example codes to create this, and I also don't understand why it is working on my home server but not my hosting. Any help would be greatly appreciated.

 

Thanks

Take out all of your suppressions (the @ sign before functions) and run it on your server.  What error(s) are you getting?

Worked out the problem. Was actually another part of code causing the issue.
