PHP Snippet 1:

EVAL "local keys = redis.call('KEYS','post:*');
      if (table.getn(keys) == 0) then return {} end;
      table.sort(keys);
      return redis.call('MGET',unpack(keys));"

PHP Snippet 2:

// a scoreless sorted set can be used as an index
SET post:1500 <value>
ZADD posts_index 0 post:1500

// Whenever you need a sorted (range) of items, you first check the index 
ZRANGE posts_index - + BYLEX 
ZRANGE posts_index [posts:1000 (posts:2000 BYLEX
