include（if.php）：无法打开流：没有这样的文件或目录

Question

我正在尝试完成Yii文档提供的用于设置Web服务的示例。文档在这里： http://www.yiiframework.com/doc/guide/1.1/en/topics.webservice

当我尝试使用http://localhost/adws/index.php/Lookup/guy查看WSDL时出现以下错误：

include(if.php): failed to open stream: No such file or directory

LookupController.php

<?php
class LookupController extends Controller
{
    public function actions()
    {
        return array(
            'guy'=>array(
                'class'=>'CWebServiceAction',
            ),
        );
    }

    /**
     * @param string of person you are asking about
     * @return if the service knows them
     * @soap
     */
    public function getAuthentication($person)
    {
       return 'To hell with '.$person;
    }
}
