How to make PHP work with subdomain and AJAX?

I work in a PHP project that uses subdomains, sessions, and Ajax. But unfortunately, I can’t get it to work! I will try to explain:

Suppose I am in this domain: app.mysite.com/index.php

In this domain, I have a form that executes an Ajax request mysite.com/functions/execute.php (without any subdomain)

In the first line of execute.php , I have require_once , which contains the helper.php file . In this file I set:

ini_set('session.cookie_domain',  '.mysite.com');
session_set_cookie_params(0, '/', '.mysite.com');
session_start();

All of the listed PHP files also contain helper.php.

If for example I run:

echo $_SESSION["myValue"];

app.mysite.com/index.php , auth.mysite.com, : ". execute.php Ajax, undefined index!

?

$.ajax({
    method   : "POST",
    url      : "https://example.com/functions/execute.php", 
    data     : myData,
    xhrFields: { 
        withCredentials: true
    }
}).done(function(result) {
    alert("success"));
});

execute.php :

ini_set('session.cookie_domain',  '.example.com');
session_set_cookie_params(0, '/', '.example.com');
session_start();
header('Access-Control-Allow-Credentials: true');

, example.php:

header('Access-Control-Allow-Origin: http://app.example.com');
