php 数组分页

public function supplys($condition,$page,$count)
    {
        $ids = $this->getIds();

        $qiu = $this->db->select("col.id AS coleid, a.title,a.addtime, c.name AS conpanyname ")
            ->from('hh_collection AS col') //求购
            ->join('hh_asktobuy AS a','col.joinID = a.id','right') // 收藏
            ->join('hh_company AS c','c.id = a.companyid','left') // 关联公司
            ->where("a.id in($ids) AND $condition")
            ->get()
            ->result_array();

        $gong = $this->db->select("col.id AS coleid, a.title,a.addtime, c.name AS conpanyname ")
            ->from('hh_collection AS col') //供应
            ->join('hh_supply AS a','col.joinID = a.id','right') // 收藏
            ->join('hh_company AS c','c.id = a.companyid','left') // 关联公司
            ->where("a.id in($ids) AND $condition")
            ->get()
            ->result_array();


        $list = array_merge($qiu, $gong);
        if($count){
            return count($list);
        }

        // 数组分页
        $count = count($list);//总条数
        $start=($page-1)*5;//偏移量，当前页-1乘以每页显示条数
        $list = array_slice($list,$start,5);

        foreach ($list as $k => $v){
            $list[$k]['state'] = 0;
        }
        return $list;
        p($list);

    }

php数组分页主要就是 array_slice函数的使用

  　　　 $count = count($list);//总条数
        $start=($page-1)*5;//偏移量，当前页-1乘以每页显示条数
        $list = array_slice($list,$start,5);
