我正在使用这个http://www.binpress.com/app/paypal-adaptive-payments-pro-codeigniter-library/140库，我正在使用它作为codeigniter项目的ipn监听器 - http://pastebin.com/pMb7Zhz3。
基本上我正在使用上面的paypal库进行并行交易，以便当用户进行付款/捐赠时，它会向2个不同的帐户汇款。一旦交易完成，paypal就会将数据发送到我的ipn监听器并解析1位客户的信息，如果我将'IPNNotificationURL' => ''留在我的代码中并进入paypal并设置ipn url就可以了。
我正在尝试获取这两个帐户的IPN信息，而不必让两个帐户都在其paypal设置中设置ipn网址。当我设置'IPNNotificationURL' => 'http://example.com/paypal_ipn'时，我仍然会获得1个帐户的ipn信息，但是我收到了我的监听器的Array to string conversion on line 11警告。我如何解决这个问题，如果我这样做，我会从两个帐户中获取ipn信息吗？
以上是我用于并行付款的库中的付款方式

我想出了如何在PHP中解析自适应支付IPN。
我将donut2d https://www.x.com/developers/paypal/forums/adaptive-payments-api/php-technique-parsing-adaptive-payment-ipn-posts?page=0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C1的DecodePayPalIPN()函数与paypal网站上的一个示例监听器结合使用，这是我的完整Codeigniter IPN侦听器，用于并行事务的自适应支付。 / p>
