PHP检查上次用户访问页面的时间

Question

I have a page login.php in which when the user login a cookie is set by the username just to ensure that if the user comes back again he need not have to log in. But now I need to specify his last visit also. How shall I do that?

Login.php

if(isset($_POST["checkbox"]) && $_POST["checkbox"]==1) {
    $expire = time() + 365*24*60*60;
}else{
    $expire = 0;
}

setcookie("user", $row['username'], $expire, "/");

The above code creates a cookie by the username as soon as the user logs in.

Also I have a file that checks if the user has already logged in and if 'yes' it doesn't let the user enter his credentials again. But now I want when the user logs in a message should appear saying "you last visited the site...".

How to do that?

Answer 1

Add a column in db table, and after each successful login update the login date and time in it.
