Php 无法获取paypal返回值

我的系统内置phpfox，有两种付款方式

一种是循环支付，另一种是平行支付

我无法在并行支付中获得返回值，但在循环选项中获得返回参数

下面是我在并行支付选项中获得的示例输出

Array ( [do] => /subscribe/complete/ [PHPSESSID] => 74b50226b0076bd66e1ddbc8baecd23d [corecf2bvisit] => 1400432842 [corecf2binvited_by_email_form] => akhil@wdstech.com [corecf2bcur_mailid] => akhil@wdstech.com [corecf2binvited_by_user] => 0 [corecf2binvited_by_email] => 0 )

但我得到了返回值，包括循环选项中的金额

我该怎么解决呢

下面给出了我的代码的详细视图
