for example, application built in php & mysql , service trying consume, provide .net c# sdk samples on website integerate. learning php webservices. question is, matter language other application uses? application need in .net c# ? or web services , api's inter operable across different programming languages ? appreciated. in advance. no. there's no need clients using same framework or language web services consume. part of point of web services enable machine-to-machine interaction in platform-agnostic way. shouldn't need "know" underlying implementation in order consume web service, how call it. example, can consume web api restful service java, c, javascript, etc. , don't need aware of fact using web api opposed different framework. by analogy, if call friend on phone, don't need know cell phone service provider is, kind of phone uses, or - need know phone number.
