[SOLVED] Session id help

[phpcode]

I know how to create a session id but what I want to know how would I make a session invalid if the user with that ID is inactive for over 1 minute?

[phpSensei]

use session_unset(); the username, and stuff.

[awpti]

Either use cookies or reset a session on every pageload checking for difference in unixtime.

 

<?php

if(!$_SESSION['last_active))
{
    $_SESSION['last_active'] = date("U");
}
else
{
    if( (date("U") - 60) > $_SESSION['last_active'] ) 
        {
            $_SESSION['valid_user'] = 0;
        }
}
?>

 

Really generic. Try to use cookies. 60 seconds is also kinda short. Guess it depends on your goal. (I didn't test the above code, that's off the top of my head, check for logic/syntax).

Or just edit the php.ini and change the session timeout to 60 seconds.

How do you know they are inactive fro 1 min?

<?php

if(!$_SESSION['last_active))
{
    $_SESSION['last_active'] = date("U");
}
else
{
    if( (date("U") - 60) > $_SESSION['last_active'] ) 
        {
            $_SESSION['valid_user'] = 0;
        }
}
?>

Doesn't work.

[redarrow]

did you read up on session_start();

<?php

if(!$_SESSION['last_active']))
{
    $_SESSION['last_active'] = date("U");
}

{
    if( (date("U") - 60) > $_SESSION['last_active'] ) 
        {
            $_SESSION['valid_user'] = 0;

Yeah, there's a typo in it As said, it's not tested. YMMV. Play a little bit, you'll figure it out.

[phpcode]

I saw the typo this is what I did to it:

 

<?php

if(!$_SESSION['last_active'])
{
   $_SESSION['last_active'] = date("U");
}
else
{
   if( (date("U") - 60) > $_SESSION['last_active'] )
       {
           $_SESSION['valid_user'] = 0;
       }
}

echo $_COOKIE["PHPSESSID"];
?>

[redarrow]

<?php session_start(); //<<< this was missing hay

if(!$_SESSION['last_active'])
{
   $_SESSION['last_active'] = date("U");
}
else
{
   if( (date("U") - 60) > $_SESSION['last_active'] )
       {
           $_SESSION['valid_user'] = 0;
       }
}

echo $_COOKIE["PHPSESSID"];
?>

[phpcode]

That doesn't create sessions.

[redarrow]

session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie.
