From what I've learned it's very similar. The main difference is directories use forward slash instead of backslash, which is why I've taken to using "DIRECTORY_SEPARATOR" instead. Functionally it's not a big deal going from a linux app to Windows because Windows will translate the path for file operations (but not for echo or print operations). Linux I don't think will translate forward slash to backslash. One of the main reasons I chose PHP is because it's considerably faster than Python for this. I'm like 99.9% sure that statement is true but I've never ported this so I can't say for certain. I've just done way less complicated loops in Python that still take way longer than this one.
