Memcache module provides handy procedural and object oriented interface
|
|
to memcached, highly effective caching daemon, which was especially
|
|
designed to decrease database load in dynamic web applications.

In the above example, an object is being saved in the cache and then
|
|
retrieved back. Object and other non-scalar types are serialized before
|
|
saving, so it's impossible to store resources (i.e. connection identifiers
|
|
and others) in the cache.
