Include_once?

[ferke]

Hi masters!

Help me please about include:
I have a module(login_auth.php) to handle session , it begins:

session_start();
session_register("session_vars");
 function setsessionvars($blah)
 {
     global session_vars;
     session_vars['login_pwd']=$blah;
 } 

Then every module begins with some code:

include ("login_auth.php"); 

If I call in a module another module, and recall this, generating a redeclare error:

In a.php:

include ("login_auth.php");
blah;
include ("b.php");
exit; 

And b.php:

include ("login_auth.php");
blah;
include ("a.php");
exit; 

If I use function include_once("login_auth.php") in a.php, the session_vars['login_pwd'] has no set when calling from b.php:

In a.php:

include_once ("login_auth.php");
echo session_vars['login_pwd']; //no value after recall!
include ("b.php");
exit; 

Can somebody help me?

Try
echo $HTTP_SESSION_VARS['login_pwd'];

or
print_r ($HTTP_SESSION_VARS);
