ใครมีวิธีทำ post data in PHP using url โดยใช้ include file php

    http://example.com/addData.php   (the other server)
    -------------------------------------
    $a_player1 = $_POST['a_player1'] = 1;            
    $a_player2 = $_POST['a_player2'] = 3;

  htto://srore.com/getdata.php
     -------------------------------------
    include("http://example.com/addData.php");
    echo $a_player1;
    echo $a_player2;

**error ???**

    Notice: Undefined variable: a_player1
    Notice: Undefined variable: a_player2


**php.ini settings then allow_url_include  เปิดแล้วครับ**
