How can browser settings affect the expiration time of a cookie set in PHP?

Browser settings can affect the expiration time of a cookie set in PHP because the browser may override the expiration time set by the server-side script. To ensure that the cookie expiration time is respected, you can set the cookie expiration time in PHP to a specific date and time in the future. This will help ensure that the cookie remains valid regardless of the user's browser settings.

// Set cookie with expiration time set to 1 hour from the current time
$expiration_time = time() + 3600; // 1 hour
setcookie("example_cookie", "value", $expiration_time);
