推荐答案

$this->load->library('image_lib');

开头 - 您只需要加载库一次，并且只有在您设置参数后。

at the beginning - you only need to load the library once, and only after you set the parameters.

然后，给出图像文件夹的相对/服务器路径，而不是url - 如base，no base_url（）。

Then, give the relative/server path to your image folder, instead of the url - as in, no base_url().

最后，检查映像所在文件夹的权限 - 它必须是可读/可写的，并且应允许php创建新文件。

Finally, check the permissions for the folder the image is in - it must be readable/writable by all, and php should be allowed to create new files.

我想这就是所有。
