最近商品--数组操作

最近商品，数组类操作

虽然是错误的。。。

if(isset($_COOKIE['cookielist'])){
            
    $cookielist = explode(",",$_COOKIE['cookielist']);
    
    if(in_array($model->no,$cookielist)){
        //如果商品存在,删除对应键值对,重新排序
        $cookielist=array_merge(array_diff($cookielist, [$model->no]));
    }else{
        //如果是新商品,删除旧列表中的最后一个
        array_splice($cookielist, 3, 1); 
    }
    
    //把浏览的商品加入数组头部
    array_unshift($cookielist,$model->no);
    
    $cookielist = implode(",", $cookielist); 
}else{
    //查询商品模型
    $prod = Product::model()->findAll([
        "condition"=> "state='Y'" ,
        "order" => "addtime DESC",
    ]);
    
    //取前四位到数组
    for ($i=0; $i<4; $i++) {
        $cookielist[]=$prod[$i]->no;
    } 
    
    $cookielist=implode(",",$cookielist);
}

//保存或更新
//保存到根目录记录一个月
setcookie("cookielist",$cookielist, time()+2592000,'/');
