php中的cURL-我有两个单独工作的函数，但是当组合起来时，第二个函数将输出第一个cURL调用的结果

我正在尝试设置fastspring订阅支付处理

我有一个包含2个函数的文件。第一个通过cURL调用他们的API并获得基本的订单信息。第二个函数通过order函数返回的subscription引用，并获取一些订阅信息

单独运行时，这两个功能都能正常工作。但是当一起运行时，第二个函数不起作用，并且输出第一个cURL调用的结果

<?php

//order reference..
$OrderReference = 'QUI110930-3371-94207B';

//UNCOMMENT THIS IF JUST WANT TO TEST getSubscriber function on its own..
//$SubscriptionReference1 = 'QUI110926-3371-68125S';

getOrder ( $OrderReference );

getSubscription ( $SubscriptionReference1 );

//test our variaables for getOrder..
echo '<br/>1:' . $OrderReferrer;
echo '<br/>2:' . $beginDate;
echo '<br/>3:' . $display;
echo '<br/>4:' . $value;

因为您使用了
定义（'XML\u POST\u URL'，$requrl）您无法使用该命令执行2个请求

不能使用define覆盖，它将始终保留第一个值。除非您在这个脚本之外的某个地方使用它（并且无法用正则变量传递变量），否则您不应该使用define

define（）。这些变量应该是常量，并且不应该更改

注意：不应使用全局变量，而应在数组或变量中返回函数的值
 您应该真正开始在函数中使用
返回。始终避免使用
globals
