Option 1

Since you are using CodeIgniter and sessions then something like this could work out for you:

set it

$someJSONobject = 'JSON';

$this->session->set_userdata('GLOBAL_JSON', $someJSONobject);

retrieve it

$someJSONobject = $this->session->userdata('GLOBAL_JSON');

echo $someJSONobject->subitem;

Make sure you are storing sessions in a DB if you go with this option because Cookie space is VERY limited

Option 2

Even if you are not using CodeIgniters' session implementation then you can do something quite similar in native PHP:

$someJSONobject = 'JSON';

$_SESSION['GLOBAL_JSON'] = $someJSONobject;

Appending on Rooneyl's solution you may want to save that value on session which is easier to access from all end

You can create a base controller with an attribute for your variable, then have your controllers extend that base controller.
