数组处理：根据不同数据库的来源信息，商户进行挑选购入后的统一操作

平台上的商品数据来自于两个互不相干的数据库，事前经过中间表进行统一处理，现在进行商户对挑选加入到自身商户商品表的操作。

直接贴代码，同样有每行解析，重要的是想出来的一种想法。

  public function add_ik(){//添加ttp到整合表    $fr_present_id=$this->input->post("fr_present_id");//接收status+goods_id+来源的库ttp还是llf+#号    //echo $fr_present_id;    $goods_id=str_replace(",","",$fr_present_id);//因为是传递多个，用逗号进行分割，所以进行对逗号的取代    $cat=substr($goods_id,-4,3);//判断来源ttp还是llf    //$status=substr($goods_id,-1,1);    //$goods_id=str_replace("$status","",$goods_id);    $hh=explode("#",$goods_id);//#号来做区分划分    $hh=array_filter($hh);//过滤空数组    //print_r($hh);    $lijunsheng=array();//开新数组    //$goods_info = array();    foreach ($hh as $value) {        $status=substr($value,0,1);        if ($status=="2") {//这个是状态，2为没选择过的商品            $cat=substr($value,-3,3);//这个是源自哪个数据库的商品            if ($cat=="llf") {//区分处理,这个是app的数据                $goods_info = array();                $value=str_replace("$cat","",$value);                $value=substr($value,1,5);                $where=array('gallery_id'=>$value);                 $llf_info=$this->gallery_model->getone_llf($where);                //print_r($llf_info);                $goods_info['goods_id']=$llf_info['gallery_id']."llf";//有做删减                $goods_info['goods_sn']=$llf_info['present_no'];                $goods_info['goods_name']=$llf_info['name'];                $goods_info['marketPrice']=$llf_info['price'];                $goods_info['costPrice']=$llf_info['sell_price'];                $goods_info['desc']=$llf_info['order_by'];                $goods_info['cat_id']=$llf_info['type_ids'];                $goods_info['original_img']=$llf_info['images'];                //print_r($goods_info);                //die;                $insert_id=$this->gallery_model->shangjia_add_goods($goods_info);                $lijunsheng[]=$insert_id;                //die;            } else {//这个是平台自身的数据                $value=str_replace("$cat","",$value);                $value=substr($value,1,5);                $where=array('goods_id'=>$value);                 $goods_info=$this->gallery_model->getone($where);//通过查商品数据库然后将信息带回到商户的商品库中                $goods_info['goods_id']=$goods_info['goods_id']."ttp";                //print_r( $goods_info);                $insert_id=$this->gallery_model->shangjia_add_goods($goods_info);                $lijunsheng[]=$insert_id;            }        }    }    if($lijunsheng != null){        exit("2");    }else{        exit("1");    }  }
