While installing the new Joomla 3.x system on your site, on step 3 – “Overview” you can see the options to install sample data set:
- Blog English (GB) Sample Data
- Brochure English (GB) Sample Data
- Default English (GB) Sample Data
- Learn Joomla English (GB) Sample Data
- Test English (GB) Sample Data

When you are trying to set or get $_SESSION variable in Joomla environment using standart approach from an external script, it appears to be empty or not set.
$_SESSION['variable_name'] = "test";
$test_var = $_SESSION['variable_name']; // $test_var is empty!?!
It happens because Joomla uses its own session handling with come unique session-id-generation and some encryption in place, so the only way to get into the Joomla session data is to use the appropriate Joomla functions. I recently had a project where I needed to make simple data-input form with captcha generator and the original captcha data was stored in (and then got from) session.
