Caching an ACL Object

[eluser]zackwragg[/eluser]
Hi all,

After having implemented Zend_ACL in my codeigniter application, I am looking to serialize the ACL object and cache it to cut down on the various overheads that can create as it gets bigger.

My question is, is there any benefit in using the Zend_Cache libraries to do this, over just using the PHP serialize function and using CodeIgniter's file helper to store it in a file. I can then use the CI file helpers to pull it out of the file and unserialize it.

Thanks for the help.
