At some point, before reaching your header() instruction, some output has been made. Your formatting is messed up, but there may be a space at the first character of the page before

<?php

but that could just be bad pasting.

Sorry for poor formatting... In my actual code there are no spaces... – Karthik Mar 02 '16 at 07:55

after your <?php starting just type this ob_start(); it will buffer empty spaces or any output before redirect.

Sorry for poor formatting.. And thanks for the replies. I have tried adding ob_start(); and die(); .. But still am facing the same error.. – Karthik Mar 02 '16 at 07:54
1st check that, are coming to proper section, means are you reaching to `header()` section or not, do some step wise testing – Qazi Mar 02 '16 at 09:20

Do few things

add ob_start just after the <?php
Place exit(); or die() after your header.
