data Ci_session codeigniter 3

Hi,

I store session in database (mysql). Everything works fine when i use classic way.

Ie : $this->session->all_userdata()


My problem is to read and unserialized data field with sql request.


it seems to be hash or something like that before serialized.

The field data looks like this :

nmTcPgiyCqgYmd-3xb7XXogEg3cJAjcIL1ILEIOD2AsS2MHlPcUmMopspw5JC6hplNpHMi8Iry0xmrWTPQTaPA..


I didnt have this on CI 2.


Can anyone help me please ?
