Object in PHP5

[eluser]Ajaxian64[/eluser]
Hello,
I would like to save in Session some informations.
I decided to store object, instead of array.
Then, I have one class, I will create some object from its.
Nevertheless my different controlers have to know the declaration of this class.
---
My question is : what is the best place in the CI framework to define the class in order some of my controlers know it.
(sorry for my english...I do my best)
Thank you

If I understand you correctly you need a class declared everywhere because you need to be able to load it from the session. (probably through serialize()/unserialize()?)

The best way to do that is probably to create a library/model and put it in the autoload.php config file. Another way would be to implement a PHP5 autoloader, you can find an example I posted here. (I haven't tried if a PHP5 autoloader works when using unserialize, I would expect it to work though)
