Twitter API showUser

[karthiksharu]

I just started working with TwitterAPI. For the below code,

 

<?php

 

include_once("twitter.lib.php");

 

$user = "//myusername";

$pw = "//mypassword";

 

$twitter = new Twitter($user,$pw);

 

$xml = $twitter->showUser("xml", $user);

 

var_dump($xml);

echo $xml;

 

?>

 

karthiksharu is my user name.

 

var dump outputs - http://twitter.com/users/show.karthiksharu? bool(false)

 

http://twitter.com/users/show.karthiksharu?  link doesnt exist.

 

Expected is an xml with tags

 

user

    id

    name

    screen

    location

    description

    profile..  and so on..

 

 

 

Can any one help me with this?????

 

thanks
