Question

Ok i made a small script, which sets a $_SESSION[$_SERVER[‘REMOTE_ADDR’]] the problem, it dont works with bots, if i go to my webpage and make page refresh it works, but it is not working with bots.

When i look in the session dir, i see 1000s of session files, with ips in it, but the session variable is always = 1, so my thinking, when the bot connects to my site, it always sets a new Session instead of increasing the session variable. Any idea how i can fix this. Here is my code:

   <?php
        session_start();
        if(isset($_SESSION[$_SERVER['REMOTE_ADDR']])){

            $_SESSION[$_SERVER['REMOTE_ADDR']]++;

            if($_SESSION[$_SERVER['REMOTE_ADDR']] % 2 == 0) {
            // DO SOMETHING
}

        } else {
            $_SESSION[$_SERVER['REMOTE_ADDR']] = 1;
        }
    ?>

EDIT FOR JON:

That script above gets executed on all pages of my site:

The Session Variable: gets build so $_SERVER[‘REMOTE_ADDR’] for example is = 127.0.0.1

so my SESSION variable would be $_SESSION[‘127.0.0.1’];

So when the IP goes, to other pages of my site x,y,1,2,3,5 the $_SESSION[‘127.0.0.1’] variable gets an increment of 1

But this dont works for bots.

Jon i thought: SESSION are serverside, so that vars get stored on the server, i dont want set any cookies.

You cannot “fix” this. If someone wants to scrape parts of your site that do not require a session being in a specific state (e.g. logged in user) then they will not bother with storing your session id cookies and returning them to you. And without a session id, each time they will look like a new session to you.

What exactly are you trying to accomplish here?
