PHP 自身擴展 SOAP 的使用詳解

工做的項目須要使用其餘公司的接口，對方給的接口是Web Service 的soap，以前沒有使用過，這兩天開始研究，瞭解了一個大概：

php 自身soap:

1.服務器端：首先完成 service.php 

服務器端的主要目的：實現客戶端發送請求的處理類，經過WSDL文件的解釋過程，完成相應的處理。

<?php
/** 
* A simple math utility class 
* @author limx
 */  
class math{  
  /** 
   * Add two integers together 
  * 
  * @param integer $a The first integer of the addition 
  * @param integer $b The second integer of the addition 
  * @return integer The sum of the provided integers 
   */  
  public function add($a, $b) {  
	return $a + $b;  
  }  
   
 /** 
  * Subtract two integers from each other 
  * 
  * @param integer $a The first integer of the subtraction 
  * @param integer $b The second integer of the subtraction 
  * @return integer The difference of the provided integers 
  */  
  public function sub($a, $b) {  
	return $a - $b;  
  }  
   
 /** 
  * Div two integers from each other 
  * 
  * @param integer $a The first integer of the subtraction 
  * @param integer $b The second integer of the subtraction 
  * @return double The difference of the provided integers 
  */  
  public function div($a, $b) {  
	if($b == 0) {  
	  throw new SoapFault(-1, "Cannot divide by zero!");  
	}  
	return $a / $b;  
  }    
}
$server = new SoapServer(math.wsdl', array('soap_version' => SOAP_1_2));  
$server->setClass("math");  
$server->handle();

math.wsdl文件：

2.客戶端：完成服務器端返回值得調用 client.php

<?php
  //$client = new SoapClient('http://10.1.7.153/soap/math.wsdl');   
  $client = new SoapClient("http://10.1.7.153/soap/service.php?WSDL");  
  try {  
  	$result = $client->div(8,2);

        preint_r($result);

} catch(SoapFault $e) {  
	print "Sorry an error was caught executing your request: {$e->getMessage()}";  
  } 
?>

以上程序的執行結果爲 : 4
