I am generating an object from the database using the following:
$game = $this->game_model->get_by('slug', 'some-title');
I am also using a cache library in Codeigniter where I write to a cache file by:
$this->cache->write($game, $cache);
where $game is the object and $cache is an identifier for that object.
I would like to generate a unique ID for this object to use as the cache name. Something like spl_object_hash but that will stay the same across subsequent instances.
For example if I do:
$cache = spl_object_hash($game);
// Cache object
$this->cache->write($game, $cache);
It will generate 000000006c5ce27300000000564a8706.cache
as the unique ID, but if I reload the page, I get a different ID, which defeats the purpose of the cache.
How can I get a consistent unique ID for an object?
