Hope this will help you :

foreach ($test as $t)   
{   
    /* this will trigger an error since $t->user_rights is an array . 
       To use explode $t->user_rights should be a string
    */                  
    $user_rights = (explode(",", $t->user_rights));
    print_r($user_rights);                                   
}

UPDATE :

If you want a comma separated values of user_rights then you have to use implode() instead of explode();

foreach ($test as $t)   
{                      
    $user_rights = implode(",", $t->user_rights);
    echo $user_rights ;                                   
}

Maybe you can convert $t using implode($t). such as: $t= explode(",", implode($t));

$t->user_rights should be string and in $t variable you will get array .so according to that array you can use array value.
