Unlike the use of their own server for Word segmentation, discuz! online Chinese word segmentation service is based on the API to return word segmentation results.

The following is based on the discuz! online Word service API written functions, testing can be normal operation:   code as follows:/**  * dz Online Chinese participle  * @param $title string for Word segmentation title  * @param $c Ontent string The content of the participle  * @param $encode The data encoding returned by the string API  * @return  array a keyword array  */ N dz_segment ($title = ', $content = ', $encode = ' utf-8 ') {    if ($title = = ") {        R Eturn false;    }     $title = Rawurlencode (Strip_tags ($title));     $content = Strip_tags ($content);     if (strlen ($content) >2400) {//Online participle service has length limit         $content =  MB_SUBSTR ($ Content, 0, $encode);    }     $content = Rawurlencode ($content);     $url = ' http://keyword.discuz.com/related_kw.html?title= '. $title.
