String concatenation compliant with Symfony2 coding style standard

Question

How could I write a long string like the following to be Symfony2 CS standard compliant?

$str = 'A very long line that' .
    'spans in multiple lines';

Now I'm getting a "Concat operator must not be surrounded by spaces" error. Any suggestion on this?

Consider using something like that:

$str  = 'A very long line that';
$str .= 'spans in multiple lines';
