preg match @ sign

[eluser]new_igniter[/eluser]
I am new to preg match but hoping someone could help me write a reg ex that would do something like the following:
I want to parse twitter feeds and pull out the content when someone posts "at" someone. This always begins with the @ sign then the name, and then the content.

How do I write something like "look for the at sign, then copy everything until there is a space after the name.

I am using get file contents, so the actual html looks like this
@<a href="/ev">ev</a>

Should be pretty simple. Maybe something like this:

Code:

// Get text from twitter
$text = get_twitter_text_here();

// Don't need linkage
$text = strip_tags($text);

// Pattern
$pattern = '/@(?<name>\w+) /';

// And find it
preg_match ($pattern , $text, $matches);

// Get our named subpattern
$name = $matches['name'];
