CI and WordPress

[eluser]phpmonster[/eluser]
Thanks for your reply.

I managed to connect to the CI db from WordPress and execute queries, however I'm using ion_auth and the userdata I need is stored in the ci_sessions user_data column with the following format:

a:5:{s:5:"email";s:19:"[email protected]";s:2:"id";s:1:"2";s:7:"user_id";s:1:"2";s:8:"group_id";s:1:"2";s:5:"group";s:7:"members";}

What format is this and how do I loop trough this.
