PHPは微信の現金引き出しを実現する(企業が小銭を支払う)

https://pay.weixin.qq.com/index.php/public/product/detail?pid=5&productType=0
どのように企業を開通して小銭を支払いますか?
商家号の製品センターにはこの機能がないものもありますが、この機能のpid(product id)は5で、ある製品に勝手に入って、住所欄でpidを5に変更します.
この機能ページにアクセスして開通しますが、条件を満たしてください.
ユーザ提示コード:

//      
 private function withdrawals_weixin($id){
        $falg = M('withdrawals')->where(['id'=>$id])->find();
        $openid = M('users')->where('user_id', $falg['user_id'])->value('openid');
        $data['openid'] = $openid;
        $data['pay_code'] = $falg['id'].$falg['user_id'];
        $data['desc'] = '  ID'.$falg['id'];
        if($falg['taxfee'] >= $falg['money']){
            return array('status'=>1, 'msg'=>"           ！" );
        }else{
            $data['money'] = bcsub($falg['money'], $falg['taxfee'], 2);
        }
        include_once PLUGIN_PATH . "payment/weixin/weixin.class.php";
        $weixin_obj = new \weixin();
        $result = $weixin_obj->transfer($data);
     
        return $result;
  }

ここでpay_コードは商家番号での現金化機能が唯一なので、再生攻撃を防ぐために、この値は決して乱数ではなく、IDで現金化記録が唯一あることが望ましい.
