My issue is what changes is needed to make in below code so just 300 characters will appear and not whole last message

please guide changes in code

2.0.7 Default theme

global $smcFunc, $scripturl;

// Topic ID

$topic = XXXX;

$request = $smcFunc['db_query']('', '

SELECT t.id_topic, m.subject, m.body

FROM {db_prefix}topics AS t

INNER JOIN {db_prefix}messages AS m ON (m.id_msg = t.id_last_msg)

WHERE t.id_topic = {int:topic}

LIMIT 1',

array(

'topic' => $topic,

)

);

list($id_topic, $subject, $body) = $smcFunc['db_fetch_row']($request);

$smcFunc['db_free_result']($request);

$body = parse_bbc($body);

echo '

<strong><a href="', $scripturl, '?topic=', $id_topic, '.0">', $subject, '</a></strong>

<p>', $body, '</p>';
