I am using PHP to generate a csv file with a first name and second name.

On my local XAMPP server it works fine and generate this output.

However on this 000webhost.com free webhosting site I get the following output.

    <br><table border='1' cellpadding='2' bgcolor='#FFFFDF' bordercolor='#E8B900' align='center'><tr><td><font face='Arial' size='1' color='#000000'><b>PHP Error Message</b></font></td></tr></table><br />

This is my code:

function outputCSV($data) 
        {
            $outstream = fopen("php://output", "w");


            function __outputCSV(&$vals, $key, $filehandler) 
            {
                fputcsv($filehandler, $vals); // add parameters if you want
            }
            array_walk($data, "__outputCSV", $outstream);
            fclose($outstream);
        }



        $result = $db->fetch_array($result);

        header("Content-type: text/csv");
        header("Content-Disposition: attachment; filename=guestlist.csv");
        header("Pragma: no-cache");
        header("Expires: 0");


        outputCSV($result);

Why is it doing this?

Is it because its a free hosting site and they are trying to put advertising in a CSV file?

How do I work around, I am a bit low on money atm so I cant afford a paid server.
Thanks
