Linux - If I delete the only file in a directory, then attempt to delete the directory  in the following statement, I get a "Directory not empty" warning. To prevent the warning:

if(is_file(adirectory/afile)) {
   if (unlink(adirectory/afile)) {
      if (is_dir(adirectory))  rmdir(adirectory);
   }
}
