สอบถามเกี่ยวกับการ upload ภาพแนวตั้ง แต่พอขึ้น server กลายเป็นแนวนอน

function resize($width, $tmp_name, $name, $type){
        $width = 500; //*** Fix Width & Heigh (Autu caculate) ***//
        $size = getimagesize($tmp_name);
        $height = round($width*$size[1]/$size[0]);
        $imgString = file_get_contents($tmp_name);
        /* create image from string */
        $image = imagecreatefromstring($imgString);
        $photoX = ImagesX($image);
        $photoY = ImagesY($image);
        $tmp = imagecreatetruecolor($width, $height);
        imagecopyresampled($tmp, $image, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
        $path = $name;

        /* Save image */
        switch ($type[0]) {
            case 'image/jpeg':
                imagejpeg($tmp, $path, 100);
                break;
            case 'image/png':
                imagepng($tmp, $path, 0);
                break;
            case 'image/gif':
                imagegif($tmp, $path);
                break;
            default:
                exit;
                break;
        }
        return true;
        /* cleanup memory */
        imagedestroy($image);
        imagedestroy($tmp);
    }

    
    
$image_path = __DIR__ . DIRECTORY_SEPARATOR . '1.jpg';

resize(100, $image_path, 'test.jpg', ['image/jpeg']);
