How to determine the remote server path: php Server file scandir

Use PHP to write a small program, view the file from the remote server, and copy the required file.
But how to determine the initial file path. if the path is specified locally, the program can run.

$ Origin = "Network \ Project \ Images"; // if the path is local, for example, "C: \...", it is correct.

Error message:


How do I write this path?

Thank you!

If http is used, you can use http: // 58.22.6.22/topics/390595943

It is best to paste your directory structure
You can use both the relative and absolute paths.

The relative path is \ Project \ Image \..
Enter \ Project \ Image \ .. in the folder window of your computer to access this folder of the VM. But this path scandir () cannot be identified. what should I do?

Thank you!
