Har inte haft anledning att testa själv, men mmCache/eAccelerator verkar ha funktioner som går att använda till detta.

Snabbt cut&paste från dokumentationen:

eaccelerator_put($key, $value, $ttl=0)
puts the $value into shared memory for $ttl seconds.

eaccelerator_get($key)
returns the value from shared memory which was stored by eaccelerator_put() or null if it is not exists or was expired.

eaccelerator_rm($key)
removres the $key from shared memory

eaccelerator_gc()
removes all expired keys from shared memory
