Did you know? (storing objects in sessions)

[sde]

When storing your custom object in a session, the object class needs to be declared before session_start();.

Wrong way

PHP Code:

<?php
session_start();

require_once('MyClass.php');

if (!$_SESSION['myobj']) {
  $_SESSION['myobj'] = new MyClass();
}

$obj = $_SESSION['myobj'] ;
?>

When the object is already stored in the session, this will generate the error:

PHP_Incomplete_Class

Right way

PHP Code:

<?php
require_once('MyClass.php');
session_start();

if (!$_SESSION['myobj']) {
  $_SESSION['myobj'] = new MyClass();
}

$obj = $_SESSION['myobj'] ;
?>

Makes sense, but had me stumped for a bit.

That's the way I'd do it anyways, but your right - I wouldn't have figured that including it after the start of the session would have caused problems, especially with that error message.
