How can the problem of cookies being deleted when closing the browser window be addressed in PHP?

When cookies are set in PHP without an expiration time, they are considered session cookies and are deleted when the browser window is closed. To address this issue, you can set an expiration time for the cookies so that they persist even after the browser is closed. This can be done by setting the time in the future when the cookie will expire.

// Set a cookie with an expiration time of 1 hour
setcookie("example_cookie", "example_value", time() + 3600);
