我正在尝试将自适应支付系统集成到我的 centos 服务器上的 codeigniter 项目中。SOAP 安装在我的服务器上（我通过 ssh 执行了“yum install php-soap”并已经重新启动了服务器），当我尝试运行时出现如下错误：

A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant XML_SERIALIZER_OPTION_INDENT - assumed 'XML_SERIALIZER_OPTION_INDENT'
Filename: SOAPEncoder/SOAPEncoder.php
Line Number: 41
A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant XML_SERIALIZER_OPTION_INDENT - assumed 'XML_SERIALIZER_OPTION_INDENT'
Filename: SOAPEncoder/SOAPEncoder.php
Line Number: 41

我错过了什么，我该如何解决？

谢谢，

也许您需要安装 XML_Serializer PEAR 包：http ://pear.php.net/package/XML_Serializer/

pear install XML_Serializer
