    $csv_output .= "\n";
				
    /* Here you could get data from the DB*/		
 	
    $csv_output .= mb_convert_encoding("Content Field 1;Content Field 2;Content Field 3;Content Field 4 \n", "ISO-8859-1", "UTF-8");				    	
    
    header("Content-type: application/vnd.ms-excel");

    /* Set your own File Name */

    header("Content-disposition:  attachment; filename= my_filename.csv");
