在php內使用SOAP

1. 建立server端的php檔案

//接收要求的函數
function request($arg1, $arg2) {
 $response = $arg1 + $arg2;
 return $response;
}
// 宣告 SOAP Server
$server=new SoapServer(NULL, array('uri'=>'http://myweb.com/'));
$server->addFunction('request'); // 定義 request 可以讓外部呼叫
$server->handle();   // 啟動 SOAP Server

2. 建立client端的php檔案

$client = new SoapClient(NULL, array('location' => 'http://127.0.0.1/soap/server.php', 'uri' =>

"http://myweb.com/"));
try {
 print_r($client->request(1, 2));
} catch (SoapFault $err) {
 echo "Web Service on Response(".$err->getMessage().")";
}

除了上面的方法,我們也可以使用wsdl來註冊soap的相關資料
1. 點此SoapDiscovery.class.php下載php產生wsdl的類別

2.將Soap.Class.php放至你的Apache之下,並在同個資料夾建立server.php

//接收端要求的參數皆定義在此
class requestClass {
 function request($obj) {
  return array('out'=>$obj->in1.','.$obj->in2);
 }
}

if (isset($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD']=='POST') {
 //這邊請輸入你的wsdl網址,也就是本php檔案的網址
 $servidorSoap = new SoapServer('http://localhost/SOAP/server.php?wsdl');
 $servidorSoap->setClass('requestClass');
 $servidorSoap->handle();
}else {
 require_once 'SoapDiscovery.class.php';

 // requestClass是要產生wsdl文件的類別名稱,SoapDiscovery是你要產生後的wsdl的命明
 $disco = new SoapDiscovery('requestClass','SoapDiscovery');
    header("Content-type: text/xml");
 if (isset($_SERVER['QUERY_STRING']) && strcasecmp($_SERVER['QUERY_STRING'],'wsdl')==0) {
  echo $disco->getWSDL();
 }
 else {
  echo $disco->getDiscovery();
 }
}

3. 建立客戶端的php檔案

 //建立客戶端連線
 $objClient = new SoapClient('http://localhost/SOAP/server.php?wsdl');
 $objResponse = $objClient->request(array('in1'=>'你好','in2'=>'呵'));
 //印出傳回結果,利用wsdl產生的結果是一個關連式陣列
 print_r($objResponse);
 //以下方法可以po出傳回的物件的型態和規格
 var_dump($objClient->__getFunctions());
 var_dump($objClient->__getTypes());
