The problem in ur code is:echo 'login success';header('Location: http://www.yoursite.com/new_page.html');sending a Location header means the browser will redirect to that page right away, so echo-ing something before it doesnt have any usethe reason it doesnt work is that http headers like Location only can be sent when theres no output yet, but in ur case there is the output 'login success'
