[Resolved] Having problem with $PHPSESSID

Xephon

ok here is my code. The $PHPSESSID always comes up as an undefined variable

<?
  session_start();
  if(isset($_POST['destroy']))
  {
      session_destroy();
      unset($_SESSION['name']);
  } else {
      if(!isset($_SESSION['name']))
      {
          $name = "Spike";
      }
  }
?>

<p>SESSID: <?=$PHPSESSID?>
<p>Name: <?=$name?>
<form action=session2.php method=post>
<input type="submit" name="reload" value="Reload Session"><br>
<input type="submit" name="destroy" value="Destroy Session">
</form>

i searched the manual and still could not find out what i was doing wrong. and yes i already set the session.save_path for windows..

here is the error i get btw:

Notice: Undefined variable: PHPSESSID in C:\Apache2\htdocs\learning\session2.php on line 15

PHP now generally has (i.e., always ships with in default configuration) the "register_globals" parameter set OFF.

Try$GLOBALS['PHPSESSID'] or $ENV['PHPSESSID'] instead ...

Chapter 7 of the manual might be worth a read ...here ...

neither of those worked, i also tried it with $GET and $POST and $_SESSION, but no luck on any of them

Well, you can definitely get it with [man]session_name/man ...

lol the name pops up as "PHPSESSID" and not the actual session file name.

man i hate trying to learn from outdated books, but php changes sooo fast that it is hard to find a GOOD book that is up to date

i needed to put session_id() instead of $PHPSESSID
