How to use Zend Cache with SimpleXML objects?

Question

I'm trying to cache the user timeline of a Twitter feed using Zend_Service_Twitter which returns its results as a SimpleXML object. Unfortunately the regular serialize functions (which Zend Cache uses) don't play nice with SimpleXMl objects. I found this http://www.mail-archive.com/[email protected]/msg18133.html.

So it looks like I'll need to create some kind of custom frontend for Zend Cache to be able to change the serialize function used. Anybody ever done this already or can point me where to look to start?

Answer 1

Instead of trying to cache the SimpleXML object, I chose to loop through Twitter posts returned and save that data as a string. I then save that string to the cache. Works for me!
