Hi, Fernando, welcome. I'm just a little unsure what you mean by "number
of company" -- is this a count, as in 10 companies, or is it a phone
number, or is it something else?

Jim's reply is workable -- storing session values is quite useful, but
sessions are tied to a specific browser client/ip, and I'm not sure
that's what you want/need here.

If you are looking for setting a global variable that will be available
everywhere in your application, you can use $GLOBALS, or set it from the
very top level context of the application. Given you're using
CodeIgniter, which sadly I am not versed in, you may need to set it with
$GLOBALS: 

$GLOBALS['my_var'] = 10; // whatever you need to do here

When you say it changes, how and when exactly does it change?
