how to delete cookies?

When I print_r($_COOKIE);, I get following result.

Array ( [filters] => Array ( [input1] => 1 [input2] => 20000 [input3] => none ) [PHPSESSID] => 12334 )

I want to delete some element and want it to be like this:

Array ( [filters] => Array ( [input3] => none ) [PHPSESSID] => 12334 )

I tried this but it not effecting anything in $_COOKIE

$past = time() - 3600;
setcookie( "filters[input1]", "", $past, '/' );
setcookie( "filters[input2]", "", $past, '/' );

What is wrong here? All day is waisted trying this?

Thanks

If you created your cookies with a domain , you may need to remove then using the same domain name. i.e.

to set a cookie:

setcookie('mycookie', 'value', time() + 999, '/', '.my.domain', false);

to delete cookie:

 setcookie('mycookie', "", -1, '/', '.my.domain', false);

Are you sure that you call setcookie() to delete the cookie with the same arguments (path, secure, etc) as you did to create the cookie?

Also, setcookie() does not affect $_COOKIE in the running script. Only subsequent calls to that script will have the modified $_COOKIE array. To remove values from $_COOKIE in the same session, call unset($_COOKIE['name']).

You must reload the page after your run setcookie() - the result of your setting cookie is not available until you reload the page. Also try using 'older' time - older than 1 hour - try like a year in the past. Some browsers will not delete cookie if the time is not far enough in the past
