This is the webservice server written by. net.
The InsertMember method must be called.

$ Client_reg = new SoapClient ("http: // 121.33.201.180: 6005/RegMember. asmx? WSDL ");
$ Functions = $ client_reg->__ getFunctions ();
// Print_r ($ functions );
$ Types = $ client_reg->__ getTypes ();
// Print_r ($ types );
$ Client_reg-> soap_defencoding = 'utf-8 ';
$ Client_reg-> xml_encoding = 'utf-8 ';//
$ Param_reg = array ('cinsertmember' => array ('name' => "Hello", 'Identity '=> "230105198311202013", 'mobile' => "15014689527 ", 'iswap '=> true), 'fellowid' => $ value, 'scardnum' => "", 'insertmemberresult' => "");
$ P_reg = $ client_reg->__ soapCall ("InsertMember", array ('parameters '=> $ param_reg ));
/*
$ Param_reg = array (
'Cinsertmember' => '',
'Name' => "Hello ",
'Identity '=> "230105198311202013 ",
'Mobile' => "15014689527 ",
'Iswap '=> True,
'Fellowid' => $ value,
'Scardnum' => "",
'Insertmemberresult' => "");
$ P_reg = $ client_reg->__ soapCall ('insertmember', array ('parameters '=> $ param_reg ));
*/
Print_r ($ p_reg );
$ Array1 = get_object_vars ($ p_reg );
Foreach ($ array1 as $ key1 => $ value1 ){
Echo $ key1. ":". $ value1 ."
 ";
}

Normally, there should be a return value.
However, my return value is null.
I suspect that the server has defined a custom method.
The input parameter of the php service causes
Thank you for your help.
------ Solution --------------------
By
Struct InsertMember {
CInsertMember objCInsertMember;
String fellowID;
String sCardNum;
}
Struct CInsertMember {
String Name;
String Identity;
String Mobile;
Boolean IsWap;
}
We can see that the InsertMember (InsertMember $ parameters) parameter should be
Array (
'Objcinsertmember' => array (
'Name' => '',
'Identity '=> '',
'Mobile' => '',
'Iswap '=> '',
),
'Fellowid' => '',
'Scardnum' => '',
)
This array does not seem to belong to you
