Re: passing an object using session var

Here's what I came up with: --script1--- <?php include('TestClass.php'); session_start(); $obj = $_SESSION['obj'];

// session_register($obj);    // recommended not to use - said to be

outdated usage ob_start(); $obj = &new TestClass(); $obj->setName('MyName'); $obj->display(); header("Location: http://localhost/~mdl/webProj/photoAlbum2/receive.php"); ob_flush(); ?> ---script2--- <?php include("TestClass.php"); session_start();

$newObj = $_SESSION['obj'];            // this works

//$_SESSION['obj'] = $newObj; // this doesn't work

$_SESSION['obj']->display();    //
$newObj->display();                        // this doesn't
$_SESSION = array();    // unsets session having effect that script fails on

every second call ?> My only remaining question is why the session fails every second time if the session is emptied and destroyed. Shouldn't script1 initialize a totally new session and populate with fresh session vars? On 11/29/06, Eric Butera <digital.tarsier@gmail.com> wrote:

see php.net manual ) in order to make an object working via session DONT SERIALIZE! its done automatically

Why am I not able to access the obj name field in script 2? thanks in advance, --script1--- <?php include("TestClass.php"); session_start(); session_register('obj');

session_register() et al are going the way of the dino. just use $_SESSION directly, just remember to call session_start() before you try to use $_SESSION

ob_start(); $obj = new TestClass(); $obj->setName('MyName');

$obj->display();        // outputs 'MyName'

header("Location: http://localhost/~lr/webProj/photoAlbum2/sessionReceiveObj.php"); // re-direct to script2 ob_flush(); ?> ---script 2---- <?php include("TestClass.php"); session_start(); $newObj = $HTTP_SESSION_VARS['obj'];

$newObj->display();       // no output, meaning no data?

$newObj->setName('Michael');

$newObj->display();      // outputs 'Michael' using obj methods

?>
