函数调用 循环 问题 求教

我想把A 函数的 返回的值 调用到 B 函数一个数组中 该怎么实现?

A函数PHP code

function get_final_price($goods_id, $goods_num = '1', $is_spec_price = false, $spec = array())
{
    $final_price   = '0'; //商品最终购买价格
    $volume_price  = '0'; //商品优惠价格
    $promote_price = '0'; //商品促销价格
    $user_price    = '0'; //商品会员价格

    //取得商品优惠价格列表
    $price_list   = get_volume_price_list($goods_id, '1');

    if (!empty($price_list))
    {
        foreach ($price_list as $value)
        {
            if ($goods_num >= $value['number'])
            {
                $volume_price = $value['price'];
            }
        }
    }

    //取得商品促销价格列表
    /* 取得商品信息 */
    $sql = "SELECT g.promote_price, g.promote_start_date, g.promote_end_date, ".
                "IFNULL(mp.user_price, g.shop_price * '" . $_SESSION['discount'] . "') AS shop_price ".
           " FROM " .$GLOBALS['ecs']->table('goods'). " AS g ".
           " LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
                   "ON mp.goods_id = g.goods_id AND mp.user_rank = '" . $_SESSION['user_rank']. "' ".
           " WHERE g.goods_id = '" . $goods_id . "'" .
           " AND g.is_delete = 0";
    $goods = $GLOBALS['db']->getRow($sql);

    /* 计算商品的促销价格 */
    if ($goods['promote_price'] > 0)
    {
        $promote_price = bargain_price($goods['promote_price'], $goods['promote_start_date'], $goods['promote_end_date']);
    }
    else
    {
        $promote_price = 0;
    }

    //取得商品会员价格列表
    $user_price    = $goods['shop_price'];

    //比较商品的促销价格，会员价格，优惠价格
    if (empty($volume_price) && empty($promote_price))
    {
        //如果优惠价格，促销价格都为空则取会员价格
        $final_price = $user_price;
    }
    elseif (!empty($volume_price) && empty($promote_price))
    {
        //如果优惠价格为空时不参加这个比较。
        $final_price = min($volume_price, $user_price);
    }
    elseif (empty($volume_price) && !empty($promote_price))
    {
        //如果促销价格为空时不参加这个比较。
        $final_price = min($promote_price, $user_price);
    }
    elseif (!empty($volume_price) && !empty($promote_price))
    {
        //取促销价格，会员价格，优惠价格最小值
        $final_price = min($volume_price, $promote_price, $user_price);
    }
    else
    {
        $final_price = $user_price;
    }

    //如果需要加入规格价格
    if ($is_spec_price)
    {
        if (!empty($spec))
        {
            $spec_price   = spec_price($spec);
            $final_price +=$spec_price; //商品价格+属性价格
        }
    }

    //返回商品最终购买价格
    return $final_price;
}

B函数
PHP code

function get_goods_properties($goods_id)
{
    /* 对属性进行重新排序和分组 */
    $sql = "SELECT attr_group ".
            "FROM " . $GLOBALS['ecs']->table('goods_type') . " AS gt, " . $GLOBALS['ecs']->table('goods') . " AS g ".
            "WHERE g.goods_id='$goods_id' AND gt.cat_id=g.goods_type";
    $grp = $GLOBALS['db']->getOne($sql);

    if (!empty($grp))
    {
        $groups = explode("\n", strtr($grp, "\r", ''));
    }

    /* 获得商品的规格 */
    //2009/11/17增加读取attr_css字段
    $sql = "SELECT a.attr_id, a.attr_name, a.attr_group, a.is_linked, a.attr_type,d.shop_price,m.user_rank,m.user_price, ".
                "g.goods_attr_id, g.attr_value, g.attr_css,g.attr_price " .
            'FROM ' . $GLOBALS['ecs']->table('goods_attr') . ' AS g ' .
            'LEFT JOIN ' . $GLOBALS['ecs']->table('attribute') . ' AS a ON a.attr_id = g.attr_id ' .
            'left JOIN'.$GLOBALS['ecs']->table('goods').'AS d ON d.goods_id=g.goods_id '.
               'left JOIN'.$GLOBALS['ecs']->table('member_price').'AS m ON m.goods_id=g.goods_id '.
            
            "WHERE g.goods_id = '$goods_id' " .
            'ORDER BY a.sort_order, g.attr_price, g.goods_attr_id';
    $res = $GLOBALS['db']->getAll($sql);
   
    
 
    $arr['pro'] = array();     // 属性
    $arr['spe'] = array();     // 规格
    $arr['lnk'] = array();     // 关联的属性
    
  



    

    foreach ($res AS $row)
  
    {
        if ($row['attr_type'] == 0)
        {
            $group = (isset($groups[$row['attr_group']])) ? $groups[$row['attr_group']] : $GLOBALS['_LANG']['goods_attr'];

            $arr['pro'][$group][$row['attr_id']]['name']  = $row['attr_name'];
            $arr['pro'][$group][$row['attr_id']]['value'] = $row['attr_value'];
            $arr['pro'][$group][$row['attr_id']]['css'] = $row['attr_css'];

        }
        else
        {    
            $arr['spe'][$row['attr_id']]['attr_type'] = $row['attr_type'];
            $arr['spe'][$row['attr_id']]['name']     = $row['attr_name'];
            $arr['spe'][$row['attr_id']]['values'][] = array(
                                                        'label'        => $row['attr_value'],
                                                       // 'price'        => $row['attr_price'],
                                                        'format_price' => price_format(abs($row['attr_price']+$row['user_price']), false),
                                                        'id'           => $row['goods_attr_id']);
        }

        if ($row['is_linked'] == 1)
        {
            /* 如果该属性需要关联，先保存下来 */
            $arr['lnk'][$row['attr_id']]['name']  = $row['attr_name'];
            $arr['lnk'][$row['attr_id']]['value'] = $row['attr_value'];
        }
    }

    return $arr;
}

主要是想在B函数里实现'format_price' => price_format(abs($row['attr_price']+$row['final_price ']), false),这句话的功能 $row['attr_price'] 是B函数的值 final_price 是A函数的值

B函数 不是 'format_price' => price_format(abs($row['attr_price']+$row['user_price']), false), 而是
'format_price' => price_format(abs($row['attr_price']+$row['final_price ']), false),这句话的功能 $row['attr_price']
