PathsReducer

The paths reducer tool accepts a list of absolute paths, and attempts to reduce them to the closest common relative path.

use AppUtils;

$reducer = FileHelper::createPathsReducer();
$reducer->addPath('/path/to/subfolder/and/file.txt');
$reducer->addPath('/path/to/subfolder/name');
$reducer->addPath('/path/to/subfolder/or/further/name.pdf');

$result = $reducer->reduce();

This will return the following reduced paths:

and/file.txt
name
or/further/name.pdf

NOTE: The tool uses realpath to resolve paths with ... in them, so symlinks will make it fail to reduce if the target file is not on the same drive.
