rmdir withour rmdir function.

Hello, I can't use the function rmdir: Warning: rmdir() has been disabled for security reasons But I do need to delete a directory with php. How can I do ? Is there any way to delete an empty directory without using the rmdir function ? I tried to use the unlink function on the directory, but It does not work, it only works for files... Thanks, Vincent.
