*/
function dz_segment($title = '', $content = '', $encode = 'utf-8'){
if($title == '' ){
return false;
}
$title = rawurlencode(strip_tags($title));
$content = strip_tags($content);
if(strlen($content)> ;2400){ //The online word segmentation service has a length limit
$content = mb_substr($content, 0, 800, $encode);
}
$content = rawurlencode($content);
$url = 'http://keyword.discuz.com/related_kw.html?title='.$title.'&content='.$content.'&ics='.$encode.'&ocs='.$encode;
$xml_array=simplexml_load_file($url); );
foreach ($result->item as $key => $value) {
