Need explanation about PHP syntax

found cosole command in Yii. And there I found method:

 public function getHelp()
 {
    $output = "This command will allow you to remove some Yii temporary data \n\n";

    return $output.parent::getHelp();
 }

I cant understand what does mean this:

 return $output.parent::getHelp();

I know this 

parent::getHelp();

call parent method. But what do full construction ?

. is the string-concatenation operator in PHP. So, the code you are looking at just returns the value of $output concatenated with the value of parent::getHelp();. If $output is foo and parent:getHelp() returns bar, then the return value is foobar.
