可以在一个soap请求中调用两个方法吗？

I create a simple wsdl and soap server with some methods. Now I want to ask you if is possible to call two methods with one soap request?

ex.

$server->_call(array=>('methodOne','methodTwo', $args);  

or i must send two soap request?

Message batching is a non-goal of SOAP. You will have to send two requests.

No, you can't. However, since you created the server, you can can simply add higher-level methods :

// low level
method1($args){
    prepare_A();
}

// low level
method2($args){
    finish_A();
}

// higher level
method3($args){
    method1($args);
    method2($args);
}
