you can add it on your plugin or theme function. I don't have any time to actually check for my answer. However, I did this long time ago and this is how much I can recall.

Warning! *Please check the wordpress codex for validity of my wordpress syntax and make sure they are not deprecated. I did this long time ago and I haven't check on their updated documentation.
*
For example, if I have a plugin called veedeoo_plug and I want to register the PHP session for this plugin in wordpress global space, then I would code it something like this.

function my_session(){

     if(!session_id()){

         session_start();
     }
}

## we need to hook the above function with the wordpress.

add_action('init','my_session');

After adding the codes above, check if there are any errors. If no errors you can assign the session as you would assign them on regular php

$_SESSION['your_session'] = 'foo_bar';

for the add_action reference, please read here.
