Re: [PHP] Understanding sessions

[Todd Cary]

If I use session_id(), I do get a value.  However, I have 
session_use_cookies = 0 and I do not have a value for SID.  Is that correct?

Todd,

I think you want the session_id() function.

I am trying to understand sessions are done with php.  My "learning
script" has the following:
  session_start();
  if (isset($_SESSION['firstname'])) {
    $_SESSION['firstname'] = 'Todd';
  } else {
    $_SESSION['firstname'] = 'Nobody';
  }
  echo "SESSION: " . $_SESSION['firstname'] . "<br>";
  echo 'SID: ' . SID . '<br>';
  echo '<br /><a href="page_2.php?' . SID . '">page 2</a>';
SID is always empty.  What have I missed?
