PHP开发SOAP注意点

1. 如果php文件都是UTF8格式的，需要注意不能有BOM头，否则会报错：looks like we got no XML document。

2. 如果php的类库文件中有执行错误，也会报错：looks like we got no XML document。

3. 需要在PHP的扩展设置中，打开PHP_SOAP选项，并重启。

4. soap配置的地址有三个地方，一个是server.php中，一个是client.php，另外就是WSDL文件

[server.php]

include_once 'SoapService.class.php'//define the php class 'Soapservice'
$server=new SoapServer('http://192.168.1.100/soap/Test.wsdl', array('soap_version' => SOAP_1_2));
$server->setClass("SoapService");
$server->handle();

[client.php]

$client = new SoapClient('http://192.168.1.100/soap/Test.wsdl);
$client->HelloWorld();

[Test.wsdl]

<service name="TestService">
<port name="SoapServicePort" binding="typens:SoapServiceBinding">
<soap:address location="http://192.168.1.100/soap/server.php"/>
</port>
</service>

[soapService.php]

class SoapService
{
/**
*
* Test the soap.
* @return string
*/
public function HelloWorld() {
return 'Hello World!';
}
}
