PHP session with redirect time

Question

I need help with a PHP user session script with waiting time, so that if there is no activity on the page it is redirected to an output page.

Answer 1

After the user has logged in, you can enter the following code snippet:

<?php

    session_start();
    session_cache_expire(1800); //o tempo é medido em segundos

?>

This way, every page that needs the user session, you should check if there is an active user session, thus:

<?

    if(!isset($_SESSION)){

        //aqui você aplica o redirecionamento
        header("Location: ".$enderecoPagina);
    }

?>
