php - php 中的 cURL - 我有 2 个单独工作的函数，但当组合时，第二个函数输出第一个 cURL 调用的结果

Question

我正在尝试设置 fastspring 订阅付款处理。

我有以下包含 2 个函数的文件。第一个通过 cURL 调用他们的 API 并获取基本的订单信息。第二个传递订单函数返回的订阅引用并获取一些订阅信息。

这两个函数在单独运行时都能正常工作。但是当一起运行时，第二个函数不工作并输出第一个 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;

Answer 1

因为您使用 define ( 'XML_POST_URL', $requrl ); 您无法使用它执行 2 个请求。

您不能使用定义覆盖，它将始终保留第一个值。除非您在该脚本之外的某个地方使用它(并且无法使用常规变量传输变量)，否则您不应该使用 define。

define() 是在(例如)配置文件中使用的一个很好的函数，您可以在其中设置需要在许多其他地方使用的 URL。这些变量应该是常量，不应该改变。

注意:您不应使用全局变量，而应在数组或变量中返回函数值。
