Why Isn't My PHP Cookie Available Immediately After `setcookie()`?

Accessing $_COOKIE Immediately After setcookie()

Problem: Why is $_COOKIE['uname'] not set immediately after calling the setcookie() function in PHP, even though it is set as expected upon the next execution of the script?

Answer: The cookie is not set until the response is sent back to the client and is not available in your PHP until a subsequent request.

However, you can set the cookie using setcookie() and then manually set the value in the $_COOKIE array:

setcookie('uname', $uname, time() + 60 * 30);
$_COOKIE['uname'] = $uname;

This will make the cookie value available immediately in your PHP script.
