Rewrite your code so the condition is evaluated *before* the headers are sent. That's cleaner PHP. — random_user_name, Oct 04 '13 at 02:39

Use output buffering and header clearing to achieve this.

ob_start()
...
if (!headers_sent()) {
  foreach (headers_list() as $header)
    header_remove($header);
}
ob_flush_end()

Untested, but give it a shot.

you have two options.

Move your header location before sending any output.
use a client side redirection and you have two ways to do this

a/ using javascript

window.location = "http://www.yoururl.com";

b/ using meta

<META http-equiv="refresh" content="5;URL=http://www.yourlink.com/new-link">

The anaswer from CP510 is good. Another way would be to use javascript to redirect the page. To quote Ryan McGeary answer, you could do either

// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");

or

// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";
