I am trying to override a setcookie to a new value. I have the following but it is not working:

$retunpage='test';
if (isset($_COOKIE['example']))
{setcookie( "example" , $retunpage );
setcookie( "auth" , "ok" ); }
setcookie( "example" , $retunpage );
setcookie( "auth" , "ok" );

Any suggestion on how I can simultaneously delete a cookie and set it again?

You should not delete the cookie to set the new value, you should simply set the new cookie with the same name and new value.

I have on the top of many pages:

setcookie( "example" , $returntopage);
setcookie( "auth" , "ok" );

However, when going to multiple pages like web page a, b and c with the setcookie (as you stated), the cookie is not overridden with the new value on each page.

For example, I have web page a, b and c. After completing forms, you can always return to the page (a, b, c) that started in all. I tried using javascript history but it doesn't accout for people who don't complete the form w/o errors.

How do you check that the cookie is not overwritten?

I check it by going to page "a" and the page creates cookie "a" as their web page. Then, I go to page "b", complete a form from page "b". Then, once the form is completed...I am routed back to page "a" instead of page "b".

Thanks all for the help. I changed all pages to

setcookie( "cookie" , $value, time()+3600, '/');
setcookie( "auth" , "ok" );

and all works great.
