Hello i need some help. I have function which delete map/submap,files etc.. but problem is that deletes all map in directory. If i have in map backup mapes with name backup1,backup2,backup3.... and if i want to delete backup1 it deletes wholl directory, soo no backup maps left, any ideas? Here is code:

Code:

function deleteAll($directory, $empty = false) {
  if(substr($directory,-1) == "/") {
   $directory = substr($directory,0,-1);
  }

  if(!file_exists($directory) || !is_dir($directory)) {
   return false;
  } elseif(!is_readable($directory)) {
   return false;
  } else {
   $directoryHandle = opendir($directory);
  
   while ($contents = readdir($directoryHandle)) {
    if($contents != '.' && $contents != '..') {
     $path = $directory . "/" . $contents;
    
     if(is_dir($path)) {
      $this->deleteAll($path);
     } else {
      unlink($path);
     }
    }
   }
   closedir($directoryHandle);

   if($empty == false) {
    if(!rmdir($directory)) {
     return false;
    }
   }
  
   return true;
  }
}

I call function with:
$dir = './backups/htdocs/' . $date .'/';
$this->deleteAll($dir,true);
