Why does the linkedin connectivity API give the wrong user id?

I have an application in php and in that I have to get all my network connection from this API.

http://api.linkedin.com/v1/people/~/connections?modified=new

But it gives an invalid item id. I checked the same API result in the LinkedIn console console ( https://developer.linkedin.com/rest-console ), but it gives a different result.

Output from the console:

<person>
    <id>nzdqEWJjKM</id>
    <first-name>Sagar</first-name>
    <last-name>Modi</last-name>
    <headline>Sr. HR Officer - Generalist at MAS Financial Services Ltd.</headline>

Exiting with rest API from my application:
