php-PHP一個方法根據傳遞值怎麼執行多次？

phpjavascript資料

php代碼

 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代碼

問題：
$type預設是OfferGetAllOfferList，當$start*$pagesize大於100時執行elseif($type == 'OfferGetAllOfferList' && $start*$pagesize>$total)裡面的代碼，$start歸1。
$start*$pagesize大於100時執行elseif($type == 'TradeOrderListGet' && $start*$pagesize>$total)裡面的代碼，結果歸1。
最後輸出“同步完成”。
遇到的問題就是第一個if執行完怎麼把$start歸1繼續往底下執行？
