Why can't I set the php cookie?

Question

PHP

Hello! On the server, there is such a hierarchy of cactologists:

site-|
       |
       |-newFolder-|
       |           |-cookie2.php
       |-cookie1.php

For some reason, I can't set the cookie from cookie2.php, while everything works from cookie1.php.
Here is the cooke1.php code:

<?php
setcookie("userid", "ralph", time()+3600);
print $_COOKIE["userid"];
?>

Ruzulat:
ralph
Everything works, I go to the browser and delete the cookie.
Now I'm trying to do the same, but from the cookie2.php file. I copy the code and as a result nothing is displayed.
What to do? What is the problem?

Answer 1

You need to specify a domain for cookies, read the setcookie documentation
