PHP - Sessions and Cookies

You want to set a cookie that is only available on the /admin path of your website. Which setcookie() call is correct?

Asetcookie('role', 'admin', time() + 3600, '/');

Bsetcookie('role', 'admin', time() + 3600, 'admin');

Csetcookie('role', 'admin', time() + 3600);

Dsetcookie('role', 'admin', time() + 3600, '/admin');

Step-by-Step Solution

Solution:

Step 1: Understand the path parameter in setcookie()
The fourth parameter defines the path on the server where the cookie is available. It must start with a slash.
Step 2: Evaluate each option
setcookie('role', 'admin', time() + 3600, '/admin'); correctly sets path to '/admin'. setcookie('role', 'admin', time() + 3600, 'admin'); misses the leading slash. setcookie('role', 'admin', time() + 3600); uses default path '/'. setcookie('role', 'admin', time() + 3600, '/'); sets path to root, not '/admin'.
Final Answer:
setcookie('role', 'admin', time() + 3600, '/admin'); -> Option D
Quick Check:
Cookie path starts with '/' [OK]

Quick Trick: Cookie path must start with '/' to restrict location [OK]
