Problem with heredoc instruction

Question

I am trying to replace HTML code with heredoc statement. However, I get a parsing error on the last line. I am sure that I did not leave a single leading space or indentation on the line of the heredoc closing tag. The following is a piece of code:

$table = <<<ENDHTML
    <div style="text-align:center;">
    <table border="0.5" cellpadding="1" cellspacing="1" style="width:50%; margin-left:auto; margin-right:auto;">
    <tr>
    <th>Show I.D</th>
    <th>Show Name</th>
    </tr>
    ENDHTML;
    while($row = mysql_fetch_assoc($result)){
            extract($row);
            $table .= <<<ENDHTML
            <tr>
                <td>$showid2 </td>
                <td>$showname2</td>
            </tr>
    ENDHTML;        
    }
    $table .= <<<ENDHTML
    </table>
    <p><$num_shows Shows</p>
    </div>
    ENDHTML; 
    echo $table;
    ?>

Where is the problem? I have a related question in addition to the above. As a coding practice, is it better to use PHP code in everything or is it better to use heredoc syntax. I mean, in PHP mode, the script bounces back and forth between the HTML and the PHP code. So what is the preferred method?
