php soap问题 跪求高手解答……！！
server端：

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?php error_reporting(7);$server=new SoapServer(null,array('uri'=>"http://test-rui"));function sayhello($str){    return "Hello ".$str;}$server->addFunction('sayhello');$server->handle();?>

로그인 후 복사

client端：

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?php error_reporting(7);try{    $client=new SoapClient(null,array('location'=>"http://localhost/php webservice/server.php",'uri'=>"http://test-rui"));    $client->sayhello("Jim");}catch (SoapFault $fault){    echo "fault code:".$fault->faultcode."<br>". "fault string : ".$fault->faultstring;}?>

로그인 후 복사

为啥客户端运行时会报错：Fatal error: Uncaught SoapFault exception: [HTTP] Not Found in D:\PHPWeb\php webservice\client.php:6 Stack trace: #0 [internal function]: SoapClient->__doRequest('__call('sayhello', Array) #2 D:\PHPWeb\php webservice\client.php(6): SoapClient->sayhello('Jim') #3 {main} thrown in D:\PHPWeb\php webservice\client.php on line 6

用try catch 后 得到这个：
fault code:HTTP
fault string : Not Found
  还有 能不能给我详细介绍下soapserver 跟soapclient方法里的那个array参数到底是怎么用的啊 ？？  
求高人帮助！！！
