无法检索php cookie值

Question

I'm trying to create a php cookie using setcookie('usrid', $user_id, time()+3600);

When I checked this with the browser, the cookie is set with the correct value passed with the variable. But I couldn't retreive the value using $_COOKIE['usrid']

I tried to delete the cookie using setcookie("usrid", "", time()-3600);, but its not getting deleted.

Now when I try to get the value of cookie, it shows the value. Can anyone tell why is this happening?

Answer 1

Finally I found the solution.

The path parameter was missing in setcookie function. When I set the path to "/", it worked.

Why it didn't work before is that I didn't provide the path parameter, so the cookie was only accessible from the path it was created. By setting the path parameter as "/", the cookie is accessible from any path of the domain.

Below is the code.

setcookie('usrid', $user_id, time()+3600, "/");
