session_encode
(PHP 4, PHP 5)
session_encode Encodes the current session data as a string
Description
string session_encode ( void )
This signature is wrong, since it assumes you want to encode the
current $_SESSION variable, but sometimes you don't want to and you want
to encode something else.
This is not specific to PHP4 only.

We are sorry, but we can not support PHP 4 related problems anymore.
Momentum is gathering for PHP 6, and we think supporting PHP 4 will
lead to a waste of resources which we want to put into getting PHP 6
ready.

Description:
------------
A custom session handler has a save function, which is given an opaque
piece of session data. No functions are provided to modify this data,
even though this can be useful in some cases.
As a workaround, session_decode and session_encode can be used.
However, there are some problems:
1. BUG:session_start() must be called in the save function; presumably
because in the save handler the session is already closed.
2. HARD TO USE:The functions do not simply take a string and return an
array or vise-versa; instead they work directly on the $_SESSION array.
This means you cannot easily use them for generic purposes.
A function that implements decode_session below could be added to the
standard library, and the existing functions deprecated, since this
function subsumes them.
Also, a similar function for encode_session.
Reproduce code:
---------------
function decode_session($session_string)
{
$current_session=session_encode();
foreach($_SESSION as $key => $value)
{
unset($_SESSION[$key]);
}
session_decode($session_string);
$restored_session = $_SESSION;
foreach ($_SESSION as $key => $value){
unset($_SESSION[$key]);
}
session_decode($current_session);
return $restored_session;
}
Expected result:
----------------
The session_string to be decoded and returned as an array.
Actual result:
--------------
An empty array is returned with no error message when above function is
called from a session save handler.
