* Thus wrote elixon:
 I guess that session_id() method will return null if session is not 
 started (not tested) so theoreticaly you can use:
 
 if (!session_id()) session_start();

This is the best method.  relying that $_SESSION is set could
falsify your reliance that the session has been started. For
example, some code may be trying to clear all session data prior to
this with:

  $_SESSION = array(); 

Even though it is really set it doesn't mean that the session has
truely started.

Is there a problem issuing multiple session_start()s for a given script?
I can't find anything in the manual that says one way or the other.
I have some scripts that call more than one functions include file and 
for convenience put a session_start() on each one.

This gives me a Notice error.
Of course I can simply use @session_start() to negate the Notice; but, 
I want to be certain this is good practice.

[elixon]

And I think that $_SESSION does not exist unless session is started =
if (!is_array($_SESSION)) session_start();
might do the job as well.
