How to use the user name as a watermark for the picture of the website?

my code uses the image of the target path as the watermark. How to change it to the user name of the uploader as the watermark? The user name tag is ["attach_name"]

if ($upload_data["is_image"] == 1)
        {
            foreach (AWS_APP::config()->get("image")->attachment_thumbnail AS $key => $val)
            {
                $thumb_file[$key] = $upload_data["file_path"] . $val["w"] . "x" . $val["h"] . "_" . basename($upload_data["full_path"]);
                if(H::isAnimatedGif($upload_data["full_path"])==0){
                    $wwater_info = getimagesize($upload_data["full_path"]);
                    $wwater_w = $wwater_info[0];//
                    $wwater_h = $wwater_info[1];//
                    if(FOX_water=="on" && ($wwater_w>=FOX_water_w && $wwater_h>=FOX_water_h)){
                        $waterImage=$_SERVER["DOCUMENT_ROOT"]."/static/water.png";//
                        H::FoximageWaterMark($upload_data["full_path"],9,$waterImage);
                    }
                }
                AWS_APP::image()->initialize(array(
                    "quality" => 90,
                    "source_image" => $upload_data["full_path"],
                    "new_image" => $thumb_file[$key],
                    "width" => $val["w"],
                    "height" => $val["h"]
                ))->resize();
            }
        }

the user name becomes a picture and then merges it. It's the same reason. Or you can merge the two libraries, directly take the user name to generate the picture, and then merge it into a watermark, so you don't have to save the user name
