我正在尝试开始使用 SOAP，我正在关注本教程： http: //www.codewalkers.com/c/a/Miscellaneous/Using-SOAP-with-PHP/3/

据我所知，我已经安装了我需要的所有东西。

soap
Soap Client    enabled
Soap Server    enabled

Directive   Local Value   Master Value
soap.wsdl_cache   1   1
soap.wsdl_cache_dir   /tmp   /tmp
soap.wsdl_cache_enabled   1   1
soap.wsdl_cache_limit   5   5
soap.wsdl_cache_ttl   86400   86400

当我尝试运行以下代码时，出现以下错误

<?php

function getStockQuote($symbol) {

    mysql_connect("localhost", "username", "password");
    mysql_select_db('captainc_general');
    $query = "SELECT stock_price FROM stockprices "
       . "WHERE stock_symbol = '$symbol'";
    $result = mysql_query($query);

    $row = mysql_fetch_assoc($result);
    return $row['stock_price'];
}


require_once('nusoap.php'); //use the nusoap library 

$server = new soap_server();

$server->configureWSDL('stockserver', 'urn:stockquote');

$server->register("getStockQuote",
                array('symbol' => 'xsd:string'),
                array('return' => 'xsd:decimal'),
                'urn:stockquote',
                'urn:stockquote#getStockQuote');

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA)
                  ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);

?>

警告：require_once(nusoap.php) [function.require-once]：无法打开流：第 17 行的 /home/captainc/public_html/soap/soaptest.php 中没有这样的文件或目录

致命错误：require_once() [function.require]：无法在 /home/captainc/public_html 中打开所需的 'nusoap.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') /soap/soaptest.php 第 17 行

任何人都知道我需要做些什么来对此进行排序？
