将 mailgun API 与 codeigniter 一起使用

Question

我正在尝试使用 mailgun api 从我的网站发送用户注册确认电子邮件。我的网站位于共享主机上。当我在本地主机（WAMP 服务器）上测试时，mailgun api 似乎运行良好。当我尝试在源代码中使用 api 时，即在控制器内部，出现语法错误。共享主机是基于 linux 的 (CentOS) 服务器。

这是错误信息。

Parse error: syntax error, unexpected '[' in /var/www/html/log2pdf/mailgun/vendor/guzzlehttp/psr7/src/functions.php on line 78

由于语法错误，我在 linux 服务器上单独下载并安装了 mailgun 依赖项（即 composer、guzzle 适配器等），因为我最初是从本地主机复制文件的（windows) 并且在 windows 和 linux 这些文件不同的印象。但这也没有什么区别。

运行 php 5.6.25 在本地主机 (WAMP) 上，php 5.3.3 在共享主机 (CentOS) 上。使用 mailgun 网页上的命令安装了所有 mailgun 依赖项。

我已尽我所能，如有任何帮助，我们将不胜感激。

这是我的控制器：

更新PHP至5.6.30版本后问题已解决。在与 Godaddy 的客户支持长时间交谈后，他们建议我更新 PHP。之后完美运行。
