Notice: Undefined variable: a_player1
Notice: Undefined variable: a_player2
php.ini settings then allow_url_include On
You're including via an absolute URL (which is a hideously bad security problem), which means you're EXECUTING that "remote" php script, and loading its OUTPUT, not the php code it contains.
And if allow_url_fopen is disabled, then nothing gets loaded anyways, and no php code will be seen, because that url is never hit.
If that file is on the same server/site as your main one, then do NOT use a url, a simple include('addData.php') will do.
What you are looking for is something like a REST API. Something like: Creating a REST API using PHP
