1.时间处理

刚刚 一天前 一个月前

public function timeCode($param)
{
    $now_time = time();
    if ($now_time - $param < 60 * 3) {
        $putTime = '刚刚';
    } else if ($now_time - $param < 60 * 60) {
        $putTime = ceil(($now_time - $param) / 60) . '分钟前';
    } else if ($now_time - $param < 60 * 60 * 24) {
        $putTime = ceil(($now_time - $param) / 60 / 60) . '小时前';
    } else if ($now_time - $param < 60 * 60 * 24 * 30) {
        $putTime = ceil(($now_time - $param) / 60 / 60 / 24) . '天前';
    } else {
        $putTime = ceil(($now_time - $param) / 60 / 60 / 24 / 30) . '月前';
        //$putTime = date('Y-m-d h:i:s', $param);
    }

    return $putTime;
}

2.敏感词判断和替换

/**
 * 
 * @param type $param
 * @return type  敏感词替换
 */
public function FilterWordReplace($param = '')
{
    $DisRedis = new \KIF\Cache\DisRedis();
    $senWord  = $DisRedis->get('senstive_word');
    $word     = preg_replace('/' . $senWord . '/i', "**", $param);
    return $word;
}

/**
 * 
 * @param type $pame
 * @return string
 * 敏感词判断
 */
public function doFilterWord($pame = '')
{
    $DisRedis = new \KIF\Cache\DisRedis();
    $senWord  = $DisRedis->get('senstive_word');

    $isWord = preg_match('/' . $senWord . '/i', $pame, $matchs);

    if ($isWord) {
        return $matchs;
    } else {
        return '';
    }
}

3.php转换\n 为html

nl2br();

4.获取文章的摘要

/**
 *  获取文章的摘要 
 *  
 * @param string $data
 * @param int $cut 字数 自定义
 * @param string $str
 * @return type
 */
public function cutArticle($data, $cut = 200, $str = "...")
{
    $data    = strip_tags($data);
    $pattern = "/&[a-zA-Z]+;/";
    $data    = preg_replace($pattern, '', $data);
    if (!is_numeric($cut)) {
        return $data;
    }
    if ($cut > 0) {
        $data = trim(mb_strimwidth($data, 0, $cut, $str));
    }
    return $data;
}

5.获取联想词

public function helper()
{
    $keyword = I('get.keyword', '', 'htmltotxt');
    $data    = file_get_contents("http://suggestion.baidu.com/su?wd={$keyword}&cb=");
    // $data =ltrim($data, "(");
    // $data =rtrim($data, ");");
    $data = iconv('GB2312', 'UTF-8', $data);
    //正则匹配所有中文
    $list   = preg_match_all("#(?:(?![，。？])[\xC0-\xFF][\x80-\xBF]+)+#", $data, $arr, PREG_PATTERN_ORDER);
    $tmpArr = $arr['0'];
    //去除重复
    $uniqueArr = array_unique($tmpArr);
    die(Json::minijson($uniqueArr));

}
