相关代码略完整的贴下，这里面有我自己的多处修改（第4行打散数组，第8行得到第一个元素）：
//上传图片
        require_once(R_P. 'hack/auction/lib/upload.class.php');//Showmsg($auctionDetail['id']);    
        $upload = new upload;
        $goods_pic = explode('.',$auctionDetail['goods_pic']);    
    if (!$auctionDetail['goods_pic']) {/***2018.8.9防止物品图片名$iconimg得到空值（新发布竞拍时没有上传图片）attachment/Mon_1808/2_2_249a5d2c05c13da.jpg***/
        $iconimg = $upload->uploadImg(randstr(6).$timestamp);
        }else{    
        $iconimg = $upload->uploadImg($goods_pic[0]);}
        /***以下两行代码解决物品介绍和活动说明转义字符替换问题2018.8.8***/
        $discription = str_replace('=','=',$discription);        
        $shuoming = str_replace('=','=',$shuoming);        
        $sqlarray = array(
                'uid'            => $winduid,
                'username'        => $windid,
                'subject'        => $subject,
                'goods_name'        => $goodsName,
                'goods_num'        => $goodsNum,
                'goods_pic'        => $iconimg,/***编辑时将物品图片名写入数据表2018.8.8添加***/
                'shop_price'        => $shopPrice,
