Re: [PHP] Uniquely identifying an array... as a key to another array

 Alright, here's the situation.  I'm wrapping memcached, which takes a list
 of several servers, into a quasi-singleton.  In other words, I want only one
 instance per set of servers, not per server.

 Assuming I had three memcached servers at localhost, 192.168.1.1 and
 192.168.1.2, I wouldn't want one instance per server, but given that there
 are seven possible permutations of combinations / only one server
 configuration, MemcacheConnector::$instances could be an array with seven
 objects.  I'm expecting MemcacheConnector::getInstance($array) to take an
 array formatted like 'server' = 'port'.

 Thusly, the question then becomes, what's the lightest possible way to store
 a unique-ish array as the key for MemcacheConnector::$instances?  Having
 MemcacheConnector::getInstance() check for
 self::$instances[serialize($serverArray)] seems a huge waste of both ram and
 CPU time.  Is there a better way?

Why not give each set of servers a name? Surely they're grouped
together for a reason, so give that reason a name.
