I think you are exploding the string wrongly. Your are explode " ", empty string. but base on you return, i assume it was in XML node format. if you print out everything, it shows all the node information, but you are only require &lt;name&gt;Afghanistan&lt;/name&gt; . Try to user simplexml_load_string, is a php function. Example in simplexml_load_string.
So you can directly access to name node. Hope this help.

PHP foreach display country name in API Call
I have a C# REST API which exposes some methods over the HTTP protocol. The API is intended to be used my my Android applocation (Java) which is currently in the makings.

Since the app is in an early development stage, and hasn't been released yet, I access the API methods using http://example.com/resources/item17 without any additional security. However, as soon as the app is released, I don't want anyone but my app users to access the API. 

My idea is to generate some kind of unique key in my C# + Android code. A simplified version to give you the idea:

int key = DateTime.Now.Minute * Math.PI * 5;


This would make the request look something like:

`http://example.com/resources/item17?key=1234567`


The C# API would verify this before sending a response. 

The only way to figure out how the key is generated would be to reverse my Android code (which will be obfuscated at that point).

Does this sound like a good solution, or do you have any other suggestions?
