What should I do if the php submission parameters are garbled?

Problem description:

PHP $_POST submits Chinese garbled characters

html: 
 
{$pro_name}

 价格：￥{$pro_price}

 已售出：{$pro_sale}件 数量    
 action: public function add(){ $user = session("user_name"); if(session("user_name")){ header("Content-Type:text/html;charset=utf8"); request.setCharacterEncoding("UTF-8"); $common = D("Common"); $data["user_id"] = $user[0]["user_id"]; $data["user_name"] = $user[0]["user_name"]; $data["pro_id"] = $_POST["pro_id"]; $data["pro_name"] = $_POST["pro_name"]; $data["pro_price"] = $_POST["pro_price"]; $data["pro_num"] = $_POST["pro_num"]; $data["pro_total"] = $_POST["pro_num"]*$_POST["pro_price"]; dump($data); echo $data["pro_name"]; } }

Why is the received $_POST["pro_name"] garbled? I have checked the source code of the page and the hidden field has not become garbled

Solution:

header("Content-Type:text/html;charset=utf8");

is changed to

echo '';
