In the provided PHP code snippet, what potential pitfalls or errors can be identified in the cookie handling logic?

The potential pitfall in the provided code snippet is that the cookie expiration time is set incorrectly. The code sets the expiration time to the current time plus 60 seconds, which means the cookie will expire immediately. To fix this issue, the expiration time should be calculated correctly by adding the desired duration to the current time.

// Potential pitfall: Incorrect cookie expiration time calculation
setcookie("user", "John Doe", time()+60, "/");

// Corrected cookie expiration time calculation
$cookie_duration = 60; // 60 seconds
setcookie("user", "John Doe", time() + $cookie_duration, "/");
