PHP error: Cannot modify header information – headers already sent

I've built a web-service with framework CakePHP. when i query the service it does return the expected content but, it also gives me an error: Warning (2): Cannot modify header information - headers already sent by. What is this and how can i resolve this?

BTW, a small tip, remove the ending `?>` from your pure php files — Kumar, Jul 10 '11 at 09:36

Could be that you try to set headers using header function after some of the content is already sent.
