求计算实际价格的算法 有时候'item_info_list' 子数组里只有一个商品 'coupon_detail_list' 子数组里只有一个优惠信息
而有时候候'item_info_list' 子数组里只有一个商品 'coupon_detail_list' 子数组里没有优惠信息,有时候'item_info_list' 子数组里只有两个商品 'coupon_detail_list' 子数组里只有一个优惠信息,有时候'item_info_list' 子数组里只有两个商品 'coupon_detail_list' 子数组里有两个优惠信息, 求大神指导 !




------解决方案--------------------
你最后想要什么结果。
------解决方案--------------------
//先预处理一下
foreach($arr['item_info_list'] as $v) $item_info_list[$v['sku_id']] = $v;
foreach($arr['coupon_detail_list'] as $v) $coupon_detail_list[$v['sku_id']] = $v;


foreach($item_info_list as $k=>$v)
echo "sku_id:$k price:" . isset($coupon_detail_list[$k]) ? $coupon_detail_list[$k]['coupon_price'] : $v['jd_price'], "
\n";

------解决方案--------------------
PHP code

foreach ($arr['item_info_list'] as $key=>$val)
{
    if(isset($arr['coupon_detail_list'][$key]))
        $arr['item_info_list'][$key] = array_merge($val, $arr['coupon_detail_list'][$key]);
}

print_r($arr);
 <div class="clear">
                 
              
              
        
            </div>
