我创建了2x1矩阵系统，其中一个人捐钱，捐赠后他从两个人那里收钱。我试图创造一种情况，即一个人第一次进入系统（注册后），系统将检查系统中是否有人可以从该人那里接收资金，如果有的话然后，我正在检查该人是否已经有两次付款，如果该人得到2次付款，系统将检查系统中的下一个人，并将再次进行该过程以检查该人是否已收到两次或不。 现在的问题是，系统只检查2个人，就好像系统找到一个人并且该人已经复活两次，支付系统将用于下一个，但如果下一个收到，则系统应该转到下一个，依此类推，除非他找到了用户或没有用户。但我的系统最多只有两个人，我不知道应该如何创建一个循环，以便系统检查数据库中的整个用户。

请帮我对数据库中的所有用户进行此系统检查。
