session.cache_expire

Anon

Hi,

For security reasons I'm wanting the session to finish if it is not active for more than 4 or five minutes. Can I use the following function:

I've seen it in my "php and MySQL Web Development" book but theres no explanation of how to implement it.

Can anyone help?? I've searched these forums but did not find anything.

Please can anyone help me end a session after a few minutes!!

$sql_select = "select * from mh_users where user_email ='$valid_user'";
$result = mysql_query ($sql_select);

      $row = mysql_fetch_array($result);

      $user_id = $row["user_id"];
      $first_name = $row["first_name"];
	  $last_name = $row["last_name"];
	  $activated = $row["activated"];

if (session_is_registered("valid_user")&&($activated == '1'))
{etc...
