The issue is this. I have several servers all running the php5-memcache extension on Ubuntu 12.04. The PHP documentation (on php.net) has several functions like cas that are not part of the default php5-extension on 12.04. The class doe have get, put, add, delete and I think extendedStats or something like that. While I haven't tried every other method of the class listed at php.net all of the other methods I have tried fail.

I assume this is because Ubuntu is using an old or modified version of the memcache class for 12.04.

So how do I fix that? Does anyone know if this is "fixed" in 14.04?
