Is the path correct? Please check

$ FileFile? This $ FileFile is from get or post.
Most servers do not enable automatic conversion of request parameters to variables.
Use $ _ GET ['filefile'] or $ _ POST ['filefile'] to try it out.

And you $ row. this variable is useless.
It is estimated that the file variable is obtained in $ row...

The local test can be downloaded. there is no error in the path. you can also enter the path to download it.

Can the local path be the same as the server path?

Thanks for your reply. the parameter conversion problem is $ FileFile. The Space server cannot automatically convert the parameter. the get method is used to solve the problem. thank you !!!
