搜索关键词高亮显示：公共方法

//srl 7-23 搜索覌點，覌點高亮变色修改function highlightDesc($content, $words, $highlightcolor = 'red') {    $wordlist = explode ( " ", $words );    foreach ( $wordlist as $hightlightword ) {        if (strlen ( $content ) < 1 || strlen ( $hightlightword ) < 1) {            return $content;        }        $content = preg_replace ( "/$hightlightword/is", "\\0", $content );    }    return $content;}

使用方法：控制器方法：使用上面方法进行高亮显示

//关键词搜索    function get_by_likename($word, $start = 0, $limit = 6) {        $topiclist = array ();        $query = $this->db->query ( "SELECT * FROM " . $this->db->dbprefix . "answer WHERE content like '%$word%' order by id desc LIMIT $start,$limit" );// var_dump($query->result_array ());die;        foreach ( $query->result_array () as $topic ) {            $topic ['title'] = checkwordsglobal ( $topic ['title'] );            $topic ['describtion'] = checkwordsglobal ( $topic ['content'] );            $topic ['title'] = highlightDesc ( $topic ['title'], $word );$topic ['describtion'] = highlightDesc (  strip_tags ( $topic ['content'] ), $word );$topiclist [] = $topic;        }        return $topiclist;    } 剥去字符串中的 HTML 标签：

strip_tags

页面中使用topiclist  函数遍历显示在页面中即可
