如何使用 Codeigniter 上传原始图像后裁剪和接收两张图像

我创建了一个只上传 1 张图像的库，并根据路径、宽度和高度对其进行裁剪。但是我不知道如何让它裁剪任意数量的图像并返回它创建的所有文件名的数组。这是我的图书馆，如果有好的方法，请告诉我。 谢谢

        $CI->load->library('upload', $config1);
        $CI->upload->display_errors('<p class="errors">', '</p>');
        //if upload do something
        if($CI->upload->do_upload())
        {
            $image_data = $CI->upload->data();
            $config2 = array(
                'image_library' => 'gd2',
                'source_image' => $image_data['full_path'],
                'new_image' => $path . '/' . $image_data['file_name'],
                'maintain_ratio' => TRUE,
                'width' => $width,
                'height' => $height
            );

            $CI->load->library('image_lib', $config2);
            $CI->image_lib->resize();
            return $image_data['file_name'];
        }
        else
        {
            return FALSE;
        }
    }
}

更新：我想通了，这是课程以及如何为任何试图做某事的人使用它。此类的作用是上传图像，并允许您根据需要创建任意数量的原始上传大小。

}

用法

$img1 = $this->up_image->upload_image();
$thumb = $this->up_image->resize($img1, 140, 120);
$img2 = $this->up_image->upload_image();
$large = $this->up_image->resize($img2, 420, 360);
