I'm having a problem with a download script. It runs fine on my local apache server, but when I put it on the my webhost's apache server, it goes crazy. Here's the script:

Code: Select all


$php_scripts = '../../php/';
require $php_scripts . 'PDO_Connection_Select.php';
require $php_scripts . 'GetUserIpAddr.php';
function mydloader($l_filename=NULL){

    $ip = GetUserIpAddr();
       if (!$pdo = PDOConnect("foxclone_data"))
      {	echo "unable to connect";
    if( isset( $l_filename ) ) {  

        header('Content-Type: octet-stream');
        header("Content-Disposition: attachment; filename={$l_filename}");
        header('Pragma: no-cache');
        header('Expires: 0');        

    else {
        echo "isset failed";

When I say "it goes crazy", I get errors saying that the header values have already been set by apparently by the PDOConnect. Then it actually reads the file. The files being downloaded are .iso, .deb, and .tar.gz. Here's a screenshot:


Any help is appreciated.

Fixed by removing blank spaces and moving the db connection code after the headers. Works on both my server and the web host.

Thanks for posting the fix! Bound to help someone running into a similar issue down the line.
