Wordpress/PHP splashscreen

Question

I would like a splashscreen (php page) showing up when a user enters my site, but only once. Any easy way to do this?

Thanks

Answer 1

Set a $_SESSION variable and check it if its set.

session_start();
if(isset($_SESSION['userwashere'])){
        //show the site code
} else {
       //show the splashscreen code
       $_SESSION['userwashere'] = true;
}
