How to implement a simple PHP webservice?

Sorry for this newbie question.

 

Could someone tell me on how to implement a simple php webservice?

 

Need something like a "Hello world" for PHP webservice

What's a PHP webservice?

hw.php

<?php
echo "<?xml version=\"1.0\" ?> 
<title>Hello World</title>";
?>

 

On the remote site call:

<?php
$hw = simplexml("http://www.othersite.com/hw.php");
echo $hw->title;
?>

 

I am unsure if that works, but that is the basic gist of what I know of a webservice. simplexml is how you would read it out, and I do not know if I setup my XML right or echo'd the object property right. So yea. The above is a real rough example that is untested.

EDIT:

For a more (much more) advanced webservice look into soap.

 

The method I have shown, is not really a "webservice" per say. But for something simple, that would work. If you are looking for a real-world solution SOAP is definitely what you are going to need to use/look into.
