Reported By: drnix@aha.ru
Status: Open
-Bug Type: Session related
+Bug Type: Documentation problem
Operating System: Windows 2000
PHP Version: 4.1.2
New Comment:
It's a mis-assumption that session_register()ing a global variable
put's it into $_SESSION in the same request.
Sessions never behaved this way.
The documentation should be clearer on this, reclassifying.

This code don't work properly:
----
<?php
session_start();
if (get_cfg_var('register_globals')) {
if (!session_is_registered('step')) {
session_register("step");
$step = 0;
}
} else {
if (!isset($_SESSION['step'])) {
$_SESSION['step'] = 0;
}
}
echo $_SESSION['step']++;
echo session_encode();
?>
<br><A HREF="<?php echo
$_SERVER['PHP_SELF']?>">Reload</A>
----
If register_globals is On, reload will increment counter.
If register_globals is Off, session will "read_only" like.
It create session file with zero length. Any write not occurs.
session_encode() returns a empty string;
