-forgot- Storing objects in a session PHP 5.2.0

[Anthony Smith]

I have read the message boards in this group and others. I still have
not been able to pull my obect out of a session and use it. Here is how
I store it in a session:

<?
//Include the UserClass & RoleClass so that we can create a user
object.
require_once("U serClass.php");
require_once("R oleClass.php");

//This has to be the first line of code a file if sessions are used.
session_start() ;

//Create a new user object
$user = new User();
$user->setName($_SERV ER['HTTP_OBLIX_GIV ENNAME']);

$role = new Role();
$role->setSysName($xm l->roles[$i]->systemName);
//Now add the role to the user object.
$user->addRole($role) ;

//Save the user object in the session
$_SESSION['user'] = $user;
?>

This is how I try to pull the object out:

<?
require_once("U serClass.php");
require_once("R oleClass.php");

session_start() ;

//Include the UserClass & RoleClass so that we can create a user
object.


//See if there is a user object in the session
if ( isset($_SESSION['user']) ){

//Get user object from session
$user = (User)$_SESSION['user'];
}

I have also just tried:
$user = $_SESSION['user'];

?>

I receive errors like these:
<b>Parse error</b>: syntax error, unexpected T_VARIABLE in
<b>/home/as411161/apache/htdocs/common/vcp_menu2.php</bon line
<b>14</b><br />

I also get this message:
<b>Warning</b>: session_start() [<a
href='function. session-start'>function .session-start</a>]: Node no
longer exists in
<b>/home/as411161/apache/htdocs/common/vcp_menu2.php</bon line
<b>5</b><br />

Hi Anthony --

This may turn out to be a dead end, but I have to ask anyway. :) Is
auto_start enabled for sessions in your php.ini file? If it is, this
might be putting the kibosh on your attempts to save an object to a
session variable.

Not like this...

Wrong again. You can't store objects into a session per se, you need to
serialize and unserialize them in order to use them in a session. Here's
something you should read:

http://php.net/manual/en/language.oop.serialization.php

When you store the object to the session, first serialize it. Then, when
retrieving it, you unserialize it.

page 1:
$_SESSION['user'] = serialize($user );

page 2:
$user = unserialize($_S ESSION['user']);

And remember to always include the class definition on all pages where you
use the class.
