unlink to delete folder?

[Zocky]

Hm, i have this intresting things going on. I red somewhere that you can't delete non-empty folder with rmdir, but i somehow manages to delete whole none-empty folder with simple unlink(folder), but this is on my localhost.

So my question is, is this how unlink works? Can you delete non-empty subfolder with unlink?

Unlink removes files, not folders. http://en.php.net/manual/en/function.unlink.php
unlink('folder') failed on my computer with the following error:
---------- Run ----------

Warning: unlink(c:\!): Permission denied in C:\1.php on line 1
PHP Warning: unlink(c:\!): Permission denied in C:\1.php on line 1
