$webservice_url = "http://120.25.XX.XX:3000/service.asmx?WSDL";//webservice地址
    $client = new SoapClientNew($webservice_url);	

	try{
	    $arr = $client->__soapCall('FunctionSQL',array('parameters' => $param));//调用其中方法
	}catch(Exception $e){
		echo $e.getMessage();
	}

1，建立新类
class SoapClientNew extends SoapClient 
{ 
  
public function __doRequest($request, $location, $action, $version, $one_way = 0) 
{ 
  
$request = parent::__doRequest($request, $location, $action, $version, $one_way); 
$GLOBALS['$soap_call_result'] = $request; //重要！此处已经返回结果，保存到全局变量中

// $start = strpos($request, '<soap');//根据实际情况做处理。。。，如果是<?xml开头，改成<?xml
// $end = strrpos($request, '>'); 
// return substr($request, $start, $end-$start+1); 
    return $request; 
} 
}

2，调用新类
$client = new SoapClientNew($webservice_url);
  try{
   $arr = $client->__soapCall('FunctionSQL',array('parameters' => $param));//调用其中方法
  }catch(Exception $e){
  }
  
  $arr = $GLOBALS['$soap_call_result']; //调用后读取全局变量，即可获得调用结果
print_r($arr);
