Store Object in PHP Session

In PHP, is it considered best practice to store the complete object as a session variable?

From my experience, sometimes it works and sometime not. Is there any specific reason for it?

Example:

session_start();
$object = new sample_object();
$_SESSION['sample'] = $object;

In general, the best practice is not to store objects in session at all :D

I would recommend to instead just store data. It will have the added benefit of making the debugging process a bit easier, when you have to inspect the current state of the session.

If you want to be really fancy, you could make a separate data mapper, that stores and retrieves data from the session for instances of that specific class (or group of classes, with the same interface).

Use serialize() in PHP before store your object, and call unserialize() when retrieve your object from session.

store object

session_start();
$object = new sample_object();
$_SESSION['sample'] = serialize($object);

retrieve object

session_start();
$object = unserialize($_SESSION['sample']);
