php-PHP一个方法根据传递值怎么执行多次？

php代码

 function one($type='OfferGetAllOfferList',$start,$pagesize=10,$total=100)    {        $next=$start+1;        if($start*$pagesize<=$total)        {            $this->outData['next'] = $next;            $this->outData['pagesize'] = $pagesize;            $this->outData['type'] = $type;            $this->outData['total'] = $total;            $this->output();        }        elseif($type == 'OfferGetAllOfferList' && $start*$pagesize>$total)        {               $this->outData['next'] = $next;            $this->outData['pagesize'] = $pagesize;            $this->outData['type'] = 'TradeOrderListGet';            $this->outData['total'] = $total;            $this->output();        }elseif($type == 'TradeOrderListGet' && $start*$pagesize>$total)        {               $this->outData['next'] = $next;            $this->outData['pagesize'] = $pagesize;            $this->outData['type'] = 'MemberGet';            $this->outData['total'] = $total;            $this->output();        }else        {            echo "同步完成";            exit;        }    }

js代码

问题：
$type默认是OfferGetAllOfferList，当$start*$pagesize大于100时执行elseif($type == 'OfferGetAllOfferList' && $start*$pagesize>$total)里面的代码，$start归1。
$start*$pagesize大于100时执行elseif($type == 'TradeOrderListGet' && $start*$pagesize>$total)里面的代码，结果归1。
最后输出“同步完成”。
遇到的问题就是第一个if执行完怎么把$start归1继续往底下执行？
