[SOLVED] Is it possible to have an instance of a class in a session?

[emehrkay]

Just something that crossed my mind.

$_SESSION['class'] = new ClassName();

and if I wanted to run a method from that session, could I do:

$_SESSION['class']->method();

??

I have not tried it, but it should work. The only restriction is that the class definition must be present before the session_start() -
[quote]If you do turn on session.auto_start then you cannot put objects into your sessions since the class definition has to be loaded before starting the session in order to recreate the objects in your session. [/quote]

Ill try it later. I didnt even think of that pf

An example of this being used is found in [url=http://www.senzalimiti.sk/slgrid/]slGrid[/url]; I've been experimenting with it lately.

I added solved too soon. It does not work

if i do
$_SESSION['dbc'] = new dbOjbect(); //that should set my database connection once and store the class as a session var

but when i go to do $_SESSION['dbc']->runQuery($query);

i get this crazy error

Please ensure that the class definition &quot;dbObject&quot; of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /homepages/sql.php on line 27
