与codeigniter一起使用mailgun API

Question

我试图使用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）上测试它时，mailgun api似乎完美地工作。当我尝试在源代码中使用api时，即在控制器中使用api时，出现语法错误。共享主机是基于Linux的（CentOS）服务器。

这是错误消息。

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

由于这是一个语法错误，我下载并安装了mailgun依赖关系（即作曲家，狂饮适配器等）分别在Linux服务器上，因为本来我从我的本地复制的文件（Windows）和是根据 的印象，这些文件是不同的Windows和Linux。但是这也没有任何区别。

在localhost（WAMP）上运行php 5.6.25，在共享主机（CentOS）上运行php 5.3.3。所有的mailgun依赖项都是使用mailgun网页上的命令安装的。

我已经尝试过所有我可以，任何帮助，将不胜感激。

这是我的控制器：

问题正在更新PHP到30年6月5日的版本后问题。经过与Godaddy的客户支持长时间的交谈之后，他们建议我更新我的PHP。它完美后工作。
