Add CC email adress on php andoutlook

I'm using php and outlook to send automatic emails. What I desire is to mention some emails on the CC. After thousands of search, I did not found any answers.

Below my script :

com_load_typelib("outlook.application");

if (!defined("olMailItem")) {
    define("olMailItem",0);
}

$outlook_Obj = new COM("outlook.application") or die("Unable to start Outlook");

$oMsg = $outlook_Obj->CreateItem(olMailItem);

$oMsg->Recipients->Add("jajaja@google.com");
