Is this encapsulation?

Question

I read many times about encapsulation, but always I see a code like this I finish wondering the same. Is it this encapsulation?

class create_active_parent{



function __construct(){
     //something
}


function clean_queues_redis(){
    //creating in this way an object, and using it, is not encapsulation, is it?
    $redis = RedisDB::fetch_instance();        
    $redis->db->flushdb();  
}

Answer 1

Encapsulation is to hide private fields from outside. $redis is just a local variable, and it will die at the end of clean_queues_redis method execution.
