SimpleXML - Problems with external file.

[<CrGeary.com/>]

Does anyone know why this doesn't work?, I am using Last.fm API, so obviously, I am limited, but this shouldn't happen.

I have 2 paths:

1. http://ws.audioscrobbler.com/2.0/?me...ser=ChrisG4620
2. http://ws.audioscrobbler.com/2.0/?me...er=ChrissG4620

URL 1, has a correct username, and URL 2, has an incorrect username, so it would show an error.

So i try running it through SimpleXML in PHP, if i parse url 1. It works fine. If i parse url 2, i get this error:

Warning: SimpleXMLElement::__construct(http://ws.audioscrobbler.com/2.0/?me...er=ChrissG4620) [simplexmlelement.--construct]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in C:\EasyPHP5.2.10\www\last.fm\includes\last_fm\test.php on line 3

This is the PHP (with the wrong username)

$result = new SimpleXMLElement( 'http://ws.audioscrobbler.com/2.0/?method=user.getInfo&api_key=cf6d5284dbbc825d5472c077c30b22ae&user=ChrissG4620', null, TRUE );

print_r($result);

Anyone got any ideas why?, If you send an incorrect username, it shows an error in XML form, so how come the SimpleXML doesn't treat it like a normal request?

Was actually curious myself, so had a look at the headers. A 400 status code is being returned by the server (as mentioned in the error message). Problem solved.
