php - headers already - Puzzling version - . Works locally, not live -

-

this question has answer here:

i aware there should no whitespace before php code. code gives me following error on live server, not on test apache server:

warning: cannot modify header information - headers sent (output started @ /home/mydomain/public_html/parts/includes/dbinfo.inc.php:5) in /home/mydomain/public_html/parts/update_part.php on line 55

i have tried removing functions.inc.phpstill getting same problem. below 2 pieces of code involved: a) dbinfo.inc.php

    <?php $username="myusername"; $password="mypassword"; $database="mydatabase"; ?>

b) update_part.php 

<?php  include("./includes/dbinfo.inc.php"); include("./includes/functions.inc.php");  mysql_connect("localhost","$username","$password") or die("error: ".mysqlerror()); mysql_select_db("$database");   //get variables transmitted form         $part_id            = $_post['part_id'];         $part_manufacturer      = $_post['part_manufacturer'];         $part_descr             = $_post['part_descr'];         $part_price         = $_post['part_price'];         $part_code          = $_post['part_code'];         $part_status            = $_post['part_status'];         $part_image             = $_post['part_image'];         $part_cat           = $_post['part_cat'];         $ave_mth_usage          = $_post['ave_mth_usage'];         $reorder_level          = $_post['reorder_level'];         $reorder_qty            = $_post['reorder_qty'];         $other_item_details             = $_post['other_item_details'];         $part_stock_taking_date         = $_post['part_stock_taking_date'];         $part_qty_in_stock      = $_post['part_qty_in_stock'];           $part_manufacturer      = mysql_real_escape_string($part_manufacturer);         $part_descr             = mysql_real_escape_string($part_descr);         $part_code          = mysql_real_escape_string($part_code);         $part_status            = mysql_real_escape_string($part_status);         $part_cat           = mysql_real_escape_string($part_cat);         $other_item_details             = mysql_real_escape_string($other_item_details);   //replace testtable name of table $sql =      "update part set          part_manufacturer       = '$part_manufacturer',         part_descr          = '$part_descr',         part_price          = '$part_price',         part_code           = '$part_code',         part_status             = '$part_status',         part_image          = '$part_image',         part_cat            = '$part_cat',         ave_mth_usage           = '$ave_mth_usage',         reorder_level           = '$reorder_level',         reorder_qty             = '$reorder_qty',         other_item_details      = '$other_item_details',         part_stock_taking_date          = '$part_stock_taking_date',         part_qty_in_stock       = '$part_qty_in_stock'       part_id = $part_id"; //mysql_query($sql) or die ("error: ".mysql_error()); do_query($sql,__line__); header("location: ./view_parts.php"); ?>

the offending code @ line 55 line before final line of b) i.e.

header("location: ./view_parts.php");

any ideas?

you should delete php closing tag php script , spaces before opening tag , again in included php scripts
