Default heredoc with period

On page 115 of the book I am receiving an error
Notice: Undefined variable: movie_details in ...table2.php on line 40
If I remove the period in the line "$movie_details .=<<<EOD" then the page loads as expected one entry to the table and without an error message. Roughly ten lines down in the file is a second heredoc written with a period style and that works without error.
With the period in the first heredoc the output from the file includes the three movie entries but then again shows the error message.
Has anyone else experienced this and how do I correct my syntax?

Hmmm. If php is like perl, then .= means take an existing variable and concatentate something with it (that's put it at the end of the existing string). As you haven't mentioned $movie_database before, it seems that your php interpreter is tripping over when it tries to add something to the end of it. So just initialize the variable first:

$movie_details = '';
$movie_details .=<<<EOD
