For each of this paths you'll have to specific whether it is a file or a directory. Or you could make your script assume, that the path is pointing to a file when the basename (the last part of the path) contains a dot.
To create a directory recursively is simple:
mkdir(dirname($path), 0755, true); // $path is a file
mkdir($path, 0755, true); // $path is a directory
0755
is the file permission expression, you can read about it here: http://ch.php.net/manual/en/function.chmod.php
