如何在php中使用c＃webservice？

I have a c# web service and one dll file, I create a php project and now need to use this web service in my project

I want to run my project on windows server 2012

How I can include the dll file in my project and use web service methods?

my c# sample code:

PMIService TestService = new PMIService();
PersonInfoVO Person = new PersonInfoVO();
Person = TestService.GetPersonByNationalCode(TB_NationalCode.Text);
MessageBox.Show(Person.FirstName + " " + Person.LastName);
