Soap .Net server & Php client Problem

i have a problem in nusoap, but there is no problem with the same code in php soap extension but my hosting provider is not allowing the php soap extension so i must use nusoap.. here is my .net soap service [WebMethod] public string Siparis(double FisTutar, double FisKdvTutari, double FisTopTutar, string CariKodu, string[] StokKodu, int[] Miktar, double[] BirimFiyat)

       {
       try
       {
           //string[] StokKodu=new string[1];
           //  StokKodu[0]="MB.236";
           //  int[] Miktar=new int[1];
           //  Miktar[0]=1;
           //  double[] BirimFiyat=new double[1];
           //  BirimFiyat[0]=100;
