 CachingHere are some incomplete and probably incorrect notes about PHP caching options. Page-level caching works well for page views that don’t change very often.

Region-level caching can be used to pull some parts of an otherwise dynamic page from a cache. Object-level caching can store structured PHP data objects, so that they don’t have to be built with each run. These levels of cache are ordered by increasing “ickiness”. PHP-Level |
