在php中存储多个$ _SESSION变量，并在另一个页面中回显它们

Question

In the same browser, not on the same domain:

If on the site A, I store in session:

session_start();
$_SESSION['fruit'] = "Apple";

---

If on the site B, I store in session:

session_start();
$_SESSION['color'] = "green";

---

How can I echo on the site C :

// Apple is green.
session_start();
$_SESSION['fruit'].' is '.$_SESSION['color'];

---

Is it possible I echo, from another domain but in the same browser, all the $_SESSION variables ?

Thanks for the help.

Short answer: No.

Long answer: Well... no but kind of yes, if you build two separate apps, one for each domain and send the session from one app to the other over an interface (e.g. a REST endpoint).
