Answer 1

You could use the build-in function realpath() for stripping slashes of existing files. But you will always end up with a canonicalized absolute pathname.

Please note that this function returns an error if the file does not exist.

Some important remarks from the docs:

realpath() expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input path and returns the canonicalized absolute pathname.

And

On windows realpath() will change unix style paths to windows style.
