Using php to export a mysql query to a downloadable .csv file

I've tried my darnest to avoid asking this question (I viewed and try a ton of examples already on the forum), most partially work which leads me to believe I'm missing something. I have a link setup to export my table into a downloadable .csv file. When I click the link the code dumps the table in csv format, BUT instead of it loading as an attachment it just displays the contents of the table in html.

--

<?php

include('bikes.php');    //db connection settings
if ($_GET['action'] == 'download')
{
header('Content-Disposition: attachment; filename="downloaded.csv"');

$query = "SELECT * FROM bikes";

$export = mysql_query ($query ) or die ( "Sql error : " . mysql_error( ) );

$fields = mysql_num_fields ( $export );

for ( $i = 0; $i < $fields; $i++ )
{
    $header .= mysql_field_name( $export , $i ) . "\t";
}

while( $row = mysql_fetch_row( $export ) )
{
    $line = '';
    foreach( $row as $value )
    {                                            
        if ( ( !isset( $value ) ) || ( $value == "" ) )
        {
            $value = "\t";
        }
        else
        {
            $value = str_replace( '"' , '""' , $value );
            $value = '"' . $value . '"' . "\t";
        }
        $line .= $value;
    }
    $data .= trim( $line ) . "\n";
}
$data = str_replace( "\r" , "" , $data );

if ( $data == "" )
{
    $data = "\n(0) Records Found!\n";                        
}

print "$header\n$data";

}
exit();

php?>

My results how up as

A, B, C, D, A, B, C, D -- I have no idea why when I click my link (download.php?action=download) that is does not prompt me to save the file to my hard drive, instead of just displaying the information on the page.

Any help would be very appreciated!

Use before sending the output: 

header('Content-Disposition: attachment; filename="downloaded.csv"');

Try this, works for me:

header("Content-Type: text/csv");
header("Cache-Control: must-revalidate, post-check=0,pre-check=0");
header("Content-Transfer-Encoding: binary\n");
header('Content-Disposition: attachment; filename="downloaded.csv"');
