Are these typos in the single user oauth ebook?

For example, setting the include_entities parameter to false, which eliminates entities from the 

user’s most recent tweet, is formatted as follows:

$connection->request('GET', 

  $connection->url('1.1/users/show'), 

  array( 'screen_name' => 'justinbieber'

  'include_entities' -> false));

I believe the code should instead be:

$connection->request('GET', 

  $connection->url('1.1/users/show'), 

  array( 'screen_name' => 'justinbieber',

  'include_entities' => false));

Cool. Well now you know about them and can fix it if you're still maintaining the book. I'm a total beginner at PHP so I just wanted to check and make sure I wasn't misunderstanding something.  This book has been a a great resource so far, thanks!
