Cache library

[eluser]displaynone[/eluser]
I would like to suggest an improvement. If your application has to cache a huge amount of data, you can get directory problems (a lot of files in the same directory), so it's a good idea to organizate the cache files in directories, p.e.:

[cache_path]/2/29/29df3630cbe4818d0569b346c527317f.cache
[cache_path]/2/29/29df3630cbe4818d0569b346c527317f.exp

So, I make this change:

Code:

function _file($cache_id, $cache_group = NULL)
{
  $hash = md5($cache_id);
  $path = $this->_group_dir($cache_group).'/'.substr($hash, 0, 1).'/'.substr($hash, 0, 2).'/';
  @mkdir($path, 0777, true);
  return $path.$hash;
}

Sorry form my english
