Comment (by TobiasBg):
[52312] added a foreach loop with the value being assigned by reference.
This can lead to weird issues later on, if the variable (here: `$path`) is
used again in the function, while the reference was not broken. While it's
not in this case, let's follow best practices and add `unset( $path );`
after the loop.
See e.g. the example at https://www.php.net/manual/en/control-
structures.foreach.php
