客户端请求文件：client.php

<?php
$client = new SoapClient("http://project:80/webserviceceshi/server.php?wsdl");//链接为senver.php的访问链接
//声明变量
$str = 'this is test string.';
//返回服务端可被调用的方法
var_dump($client->__getFunctions());
//调用
$data=$client->str($str);
//$data=$client->say();
//格式化输出数据
var_dump($data);

执行后返回结果：

array (size=2)
0 => string 'string str(string $str)' (length=23)
1 => string 'string say()' (length=12)

string 'this is test string.' (length=20)
