如何使php更加统一

Question

我希望使用php更新数据库中的表。 我正在使用php统一开发游戏来检索和更新数据。 每个用户都使用他们的FB详细信息登录（使用FB API的正确方法），但是现在，用户名是唯一的int ID和需要更新的sc列。

这是一个链接示例： http : //www.mydomain.co.za/php/myphp2.php?id= 1&sc = “ 1,2”

PHP代码（myphp2.php）：

<?php

require_once('/home/########/public_html/php/mysqli_connect.php');
$id = $_GET['id'];
$selected_cards = $_GET['sc'];

$query = "UPDATE PlayerCards SET SelectedCards=$selected_cards WHERE ID=$id";

$response = @mysqli_query($dbc, $query);

if($response){
    echo 'Updated the sc of the selected id';

} else {
    echo 'could not execute database query 2';
}
?>

这样，我可以使用浏览器更新任何用户的sc值。 （大问题）

这是我的Unity C＃脚本，用于检索我将在数据库中用于存储值的facebook用户的登录ID：

我可以连接到Unity中的数据库，以便它访问数据库以更新表。 统一连接时仅授予更新特权。 然后可以用脚本将id和sc括起来（将php嵌入脚本中）以更新表。 用户可以在脚本中更改ID吗？ 部署游戏时，用户可以编辑脚本吗？

当用户使用Facebook凭据登录时，请在会话变量中设置其ID。 在sql查询中使用会话变量，以便只有用户才能更新其卡。
