Sweethearts - heart task (last task)

I have this code, but it’s not passing the last test case. Not sure how to indent the asterisks properly.

public function pair(string $a, string $b): string
{
    $initialsLine = "**     {$this->initials($a)}  +  {$this->initials($b)}     **";

    return <<<HEART
         ******       ******
       **      **   **      **
     **         ** **         **
    **            *            **
    **                         **
    $initialsLine
     **                       **
       **                   **
         **               **
           **           **
             **       **
               **   **
                 ***
                  *
HEART;
}

What does the test output say?

Please use codeblocks and not images to share text.

Can you tell what is different between the actually and expected outputs?

@rvemuri2 Please read the PHP documentation on Heredoc syntax. You will find all information on how to indent the string, so the test will pass. I hope this helps!
