What will be the output of the following PHP code?

setcookie('user', 'Alice');
if(isset($_COOKIE['user'])) {
  echo 'User is ' . $_COOKIE['user'];
} else {
  echo 'User cookie not set';

CUndefined index error

DUser is Alice

Step-by-Step Solution

Solution:

Step 1: Understand when cookies are available
Cookies set by setcookie() are sent to the browser and only available in $_COOKIE on the next request, not the current script.
Step 2: Analyze the code behavior
The isset($_COOKIE['user']) check will fail because the cookie is not yet available in the current request.
Final Answer:
User cookie not set -> Option A
Quick Check:
Cookies available next request = User cookie not set [OK]

Quick Trick: Cookies appear in $_COOKIE only on next page load [OK]
