Question

I am having an issue after I unset a cookie in php. This is my code

controller.php

setcookie("alert",'String',time()+3600,'/');
header("Location: ../home.php");

home.php

if(!empty($_COOKIE['alert']) && $_COOKIE['alert'] != ''){

    malert($_COOKIE['alert']);

    $_COOKIE['alert'] = '';
    setcookie('alert', '', time()-1000);
    setcookie('alert', '', time()-1000, '/');           
print_r($_COOKIE);

   }

When the home page loads the function malert works. But I expect it to skip the if condition when the page is refreshed again.. The problem is even after refreshing the home.php again , it is entering the if condition. Am i missing any information here on page refresh about cookie.?

The print_r output is

Array ( [PHPSESSID] => xxx [alert] => String )
Array ( [PHPSESSID] => xxx [alert] => )

Note: As I am using .htpassword in this folder I am not able to use SESSION

You’re calling setcookie() after print_r(). You can’t call setcookie() after outputting content because headers are already sent.
