PHP实现模糊搜索中文分词

1.下面代码复制到公共函数累里面

/** * 模糊搜索中文分词 */function decorateSearch_pre($words){    $tempArr = str_split($words);    $wordArr = array();    $temp = '';    $count = 0;    $chineseLen = 3;    foreach($tempArr as $word){        if ($count == $chineseLen){            $wordArr[] = $temp;            $temp = '';            $count = 0;        }        // 中文        if(ord($word) > 127){            $temp .= $word;            ++$count;        }else if (ord($word) != 32){            $wordArr[] = $word;        }    }    if ($count == $chineseLen){        $wordArr[] = $temp;    }    return '%'.implode($wordArr, '%').'%';}

2.ThinkPHP后台控制器调用实例：

    /**     * 搜索功能     */    public function search() {        //获取查找的内容        $search = $_POST['text'];        if($search) {            $search = decorateSearch_pre($search);            $map = [                'content' => ['like', "%{$search}%"]            ];            //分页处理            $count = M('ask')->where($map)->count('id');            import('ORG.Util.Page');            $page = new Page($count,15);            $limit = $page->firstRow . ',' .$page->listRows;            $this->result = D('AskView')->order('time DESC')->limit($limit)->where($map)->select();            $this->page = $page->show();            $this->display();        } else {            redirect($_SERVER['HTTP_REFERER']);        }    }
