How add array to redis?

Question

participants I use REDIS database and use PHP client http://rediska.geometria-lab.net/documentation/ Here i found type Sorted sets and try create users list for current user. My code is:

$sortedSet = new Rediska_Key_SortedSet('userslist'); // use collaction userslist
        $sortedSet[1] = array('name' => 'Max');
        $sortedSet[1] = array('name' => 'Vasile');

As I understand userslist indicates the name of the collection, and the number 1 in $ sortedSet [1] key. Then, in the console through the client redis-cli write:

127.0.0.1:6379> SMEMBERS 1: userslist 
(empty list or set) 
and get a empty blank ... prompt, what am I doing wrong? May be my concept is wrong?

The sorted set commands is prefixed with Z.

http://redis.io/commands#sorted_set

Try:

ZRANGE userslist 0 -1

SMEMBERS is set not SORTED SETS for sorted sets USE ZSETS

 ZADD myzset 3 "two"
 ZRANGE myzset 0 -1 WITHSCORES

ZADD expects 3 parameters key, score and member, You are not providing it in your code

ZADD myzset 1 "one"
ZADD myzset 1 "uno"

You will have to use ZRANGE to get the range from sorted sets

ZRANGE myzset 0 -1   // This will give all values in SETS

I do not know how the PHP library works but it seems you have overwriting the members

$sortedSet[1] = array('name' => 'Max');
$sortedSet[1] = array('name' => 'Vasile');

Use Monitor command on redis-cli it will help you to analyze which command redis is processing. So start redis-cli and type monitor and then run your script and check in redis-cli which command it is firing

redis-cli monitor

TIP: Try not to write any code until you understand how things works. E.g. In this case try to understand the difference between SETS and ZSETS
