| Hi, I recently upgraded from php4/apache1.3 to php5/apache2.2. Now some topics on the forum don't display any more. In the errorlog is this error: 8: Undefined offset: 0 File: /home/xxx/public_html/joomla/components/com_smf/smf.class.php Line: 455 or 8: Undefined offset: 0 File: /home/xxx/public_html/joomla/components/com_smf/smf.class.php Line: 449 This is line 441-462 from smf.class.php. It has something to do with $matches[0] returning a empty value I think. Something similair as in this topic: http://www.joomlahacks.com/component/option,com_smf/Itemid,94/topic,2503.0 Only there it is a notice, and on my site the forum disappears. Code: if (empty($headers) || empty($keywords) || empty($css)) { //if one is empty rebuild all $headers = ''; $keywords = ''; $css = ''; $this->debug .= 'loading headers'; $regex = '/<head>.*<\/head>/smi'; preg_match($regex, $buffer, $matches); $headers = $matches[0]; $regex = '/name="keywords" .*" \/>/i'; preg_match($regex, $headers, $matches); $search = array ('/.*content="(.*)".*/i'); $replace = array ('$1'); $keywords = preg_replace($search, $replace, $matches[0]); $regex = '/<link rel="stylesheet" .*" \/>/'; preg_match_all($regex, $headers, $matches); foreach ($matches[0] as $key => $val) { $css .= $val."\n"; } Could someone please help? |
