Create a webservice in Php native

I am new in web service. I was totally 开发者_开发技巧confused when seeing examples to create web service in internet. Actually, My client have xml to place the orders. what they want is they need to create a wsdl(web service) to call the xml by their vendor forms. So i need to create a webservice that integrate with xml and vendopform(it may be in any language). How i can do this, my mind has empty now to think this. Can any body help me to sort this issue.

If you're creating a SOAP service (which it sounds like you are, and I feel sorry for you ;)), try starting by looking at PHP's SOAP extension:

http://php.net/manual/en/book.soap.php

If you can create something more RESTful, Ruby on Rails does a good job at allowing you to throw together a quick and dirty web service without too many headaches, but even in PHP you can create RESTful APIs pretty easily.

You can read the HTTP request body via e.g. fgets(STDIN) if your requests will accept XML as a POST/PUT format.

But yes, your question is too broad to provide anything more than nudges towards the tools you might choose to use.
