pre > code with blank lines

Blank lines should be ignored by the script when creating the ol.

$code = trim(file_get_contents('./highlight.php'));

 
ini_set('highlight.comment', 'comment');
ini_set('highlight.default', 'default');

ini_set('highlight.keyword', 'keyword');

$code = highlight_string($code, TRUE);
 
/* Clean Up */

$code = substr($code, 33, -16);
$code = str_replace(' ', ' ', $code);

$code = str_replace('<br />', "\n", $code);
$code = str_replace('<span style="color: ', '<span class="', $code);

 
/* Normalize Newlines */
$code = str_replace("\r", "\n", $code);

while (strpos($code, "\n\n\n") !== FALSE) {
    $code = str_replace("\n\n\n", "\n\n", $code);
