php only get variable values from double quote strings.
So you can use heredoc or nowdoc(php5.3):

Heredoc:

Code:

foreach ($myquery_domain->result() as $row ){
    $domain = $row->domain;
    $domain_id = $row->domain_id;
    echo <<<EOT
<tr>
<td>
  <span class="flip_domain" id="{$domain_id}">+</span>{$domain}
</td>
</tr>
EOT;
}

heredoc is more strict but you can get more maintanable code.
