Redis error: ERR Protocol error: invalid bulk length Redis command was: hmset Array

[wanghaozi]

with the demo usage:
$result = $redis->hmset(['test_collection', 'key1', 'val1', 'key2', 'val2']);
got the errors:
Database Exception – yii\db\Exception Redis error: ERR Protocol error: invalid bulk length Redis command was: hmset Array
fix the invoke codes with :
$result = $redis->hmset(['test_collection', 'key1', 'val1', 'key2', 'val2']);
seems work. If the documentation is wrong , please fix it.thx

Umm... I see no difference:

 $result = $redis->hmset(['test_collection', 'key1', 'val1', 'key2', 'val2']); // demo 
 $result = $redis->hmset(['test_collection', 'key1', 'val1', 'key2', 'val2']); // your proposed fix

sorry for the confusion.
the usage should be
$result = $redis->hmset('test_collection', 'key1', 'val1', 'key2', 'val2');
