With PHP, the connections to the
associated Apache instance remain running. When adding or removing servers from the list in a
running instance (for example, when starting another script that mentions additional servers), the
connections are shared, but the script only selects among the instances explicitly configured within the
script.
To ensure that changes to the server list within a script do not cause problems, make sure to use the
consistent hashing mechanism.

To install, extract the package and then run install.rb:

require 'memcache'
memc = MemCache::new '192.168.0.100:11211'
You can add a weight to each server to increase the likelihood of the server being selected during
hashing by appending the weight count to the server host name/port string:
require 'memcache'
memc = MemCache::new '192.168.0.100:11211:3'
To add servers to an existing list, you can append them directly to the
memc += ["192.168.0.101:11211"]
To set data into the cache, you can just assign a value to a key within the new cache object, which
works just like a standard Ruby hash object:
memc["key"] = "value"
