After reading the following posts I have a few questions:
How can I send and receive data to and from a URL, i.e. server side scripts, web services, etc?

Is it possible to send and recieve data from/to a MySql server?

I guess this is more of a PHP question so I still hope it applies here.

I was wondering if anyone knew of any examples of a php server side script that can accept unity GET request, extract out the parameters and then inset those parameters into a function (this function I will use to query my database)

From what I understand from the UNITY side, I can pass the URL + Parameters through the WWW class to initiate the GET request.

var url = "http://example.com/script.php?var1=value1&var2=value2";
WWW www = new WWW(url);
///And So on

So the question is how i set up my PHP script to be able to do something with this request.

I think I can start out with the following in my php script

<?php

 if (isset($_GET['url'])) 
 {
	$url = $_GET['url'];
 }

?>

Am I understanding this correctly that this will set $url to http://example.com/script.php?var1=value2&var2=value2 ?

If this is correct I should then be able to parse out my parameters into an array that I can feed into my query function. Using a series of string manipulators.

Once I have this array I should be able to feed them into my function:

 <?php

function Query(value1, value2)
{
   //do some awesome Query stuff
   return result;
}
?>

Assuming I have everything right up until now, this is where I get stuck, How to I take the result of my function so that it get sent back to the www result of my unity script?

For your example:

var url = "http://example.com/script.php?var1=value1&var2=value2";
WWW www = new WWW(url);

Script might be:

<?php

 if (isset($_GET['var1'])) 
    $var1 = $_GET['var1'];
 if (isset($_GET['var2'])) 
    $var2 = $_GET['var2'];
 echo ("got $var1 and $var2");
?>

and your www object will get it in .text like

  var result = www.text; // result should now be 'got value1 and value2'
