This is my array
 Array (
    [camp] => 1523270715437137241
    [seg] => Array
        ([0] => Array
                ( [id] => 1524043028577447661
                    [ben] => 10000
                    [rule] => Array
                        ([0] => Array
                                ([id] => 1524050160515158364
                                    [logic] => #3 and # 4
                                )))))
I want to get the values belongs to 'rule' array which is inside three big arrays without using foreach loop. Is it possible?
