PHP Redis

Description

Return value

An array of elements, the contents of the set.

Example
$redis->delete('s');
$redis->sAdd('s', 'a');
$redis->sAdd('s', 'b');
$redis->sAdd('s', 'a');
$redis->sAdd('s', 'c');
var_dump($redis->sMembers('s'));

Output:

array(3) {
  [0]=>
  string(1) "c"
  [1]=>
  string(1) "a"
  [2]=>
  string(1) "b"
}

The order is random and corresponds to redis' own internal representation of the set structure.

结果集的顺序是随机的,这也符合Redis本身对SET数据结构的定义。不重复,无顺序的集合。
