贝宝退货？PayerID=

支付完成后PayPal 返回index.php?PayerID=N3QKU3H2STQZN，我的 addCash 函数被忽略。

它在以前的网络服务器上工作（已删除），我不知道我在 php.ini 上是否缺少任何扩展

系统信息 Centos 7 +PHP 版本 7.4.28

头文件.php

$paypal_email = getJsonSettings("paypal");

付款完成后执行的函数 AddCash。

function addCash($account_id, $coins)
    {
        global $database;

        $stmt = $database->runQueryAccount("UPDATE user SET credit = credit + ? WHERE id = ?");
        $stmt->bindParam(1, $coins, PDO::PARAM_INT);
        $stmt->bindParam(2, $account_id, PDO::PARAM_INT);
        $stmt->execute();
    }
