我希望使用php更新数据库中的表。我正在使用php开发一个统一的游戏来检索和更新数据。每个用户使用他们的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。
以下是一个链接示例：http://www.mydomain.co.za/php/myphp2.php?id=1&sc=“1,2”
<?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';
}
?>
这样我就可以使用浏览器更新任何用户的 sc 值。 （大问题）
以下是Unity的C＃脚本，用于检索我将在数据库中用来存储值的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。在单位内连接时仅提供更新权限。然后， id 和 sc 可以被脚本包含（将php嵌入到脚本中）来更新表。用户是否可以更改脚本中的 id ？在部署游戏时，用户是否可以编辑脚本？

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session变量，以便只有用户才能更新他们的卡。
