include '../index.php';
include '../public_html/home/xxxxx/index.php';

but its not working. Now I want to include header.php from main domain in index.php which is in sub domain. By using the include function I get the error failed to open stream: No such file or directory in /home/content/xx/xxx/xxxx/xxx/

I know that this error occurs when a file does not exists on the given mentioned path, but how can I include a file from main domain to subdomain? thank you in advance

You can use the full patch.Without any problem

 define("URLSITEPATH1",(isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]");
include URLSITEPATH1.'/index.php';
include URLSITEPATH1.'/YourPatch/index.php';
